Extra Charges During Product Exchange: Your Consumer Rights

If a shop advertises a "one-on-one" or "buy one, get one" exchange scheme and then quietly adds a charge you were never told about, that is not just bad service, it can be an unfair trade practice you can challenge. Consumer commissions have repeatedly held retailers liable for collecting money over and above what a promotional scheme promised. The principle behind those orders matters to every shopper: a seller is legally bound by the exact terms it advertises, and demanding hidden charges over the promised price can attract liability under the Consumer Protection Act, 2019.

This article explains, in plain English, why extra charges during a product exchange offer can be illegal, what counts as an unfair trade practice or a deficiency in service, which exact sections of the Act you rely on, what a complaint costs, how long it takes, and the practical steps to recover your money and claim compensation.

What a "one-on-one" exchange scheme actually promises

A one-on-one exchange offer (often marketed as "buy one, get one free" or "exchange your old product, get a new one") is a promotional promise. When a retailer publishes the terms, for example, "give us your old item plus the listed price and take the new product", those terms become the basis of the deal the consumer relies on.

The legal idea here is simple: an advertisement is an invitation to offer, and once the customer accepts the advertised terms and pays, a binding transaction is formed on those terms. If the retailer then demands an amount over and above what was advertised, without clearly disclosing it in advance, the customer has been made to pay more than the promised price for the same promised benefit.

That gap between what was promised and what was charged is where consumer law steps in. It does not matter whether the extra money is described as a "handling charge", a "scheme adjustment", a "logistics fee", an "exchange bonus recovery" or simply added to the invoice with no label at all. What matters is whether the total the consumer had to pay exceeded the total the advertisement led the consumer to expect, and whether the difference was disclosed clearly and in advance.

The statutory framework, section by section

The Consumer Protection Act, 2019 replaced the Consumer Protection Act, 1986 and came into force in stages from July 2020. Most of the sections that decide an exchange-offer dispute sit in the definitions clause, section 2. It is worth knowing them precisely, because a complaint that names the right sub-clause is much harder for a retailer to talk its way out of.

Two more provisions are worth knowing even though they are not the ones you personally enforce. Section 21 lets the Central Consumer Protection Authority direct a trader to discontinue or modify a false or misleading advertisement and impose a penalty of up to Rs 10 lakh on a manufacturer or endorser, rising to Rs 50 lakh for repeat contraventions. Section 89 makes a false or misleading advertisement by a manufacturer or service provider that is prejudicial to consumers punishable with imprisonment up to two years and a fine up to Rs 10 lakh, and up to five years and Rs 50 lakh for a subsequent offence. Those are enforcement levers you can point to in correspondence, and they explain why a well-drafted legal notice often produces a refund within days.

If the extra money took the billed amount above the maximum retail price printed on the pack, there is a separate and parallel wrong. Under the Legal Metrology Act, 2009 and the Legal Metrology (Packaged Commodities) Rules, 2011, a pre-packaged commodity must conform to the declarations on the package, and section 36 of that Act penalises selling a pre-packaged commodity that does not conform to those declarations with a fine that can extend to Rs 25,000 for a first offence and higher amounts for repeats. You can pursue this through the Legal Metrology department of your state in addition to, not instead of, the consumer complaint. The bare text of every Act named here is available on the official India Code portal; the specific sections are set out here so you can look them up directly.

Beyond the definitions you enforce yourself, three provisions are what give a demand letter its teeth.

Note: Section numbers cited here are from the Consumer Protection Act, 2019. Always verify the current section text on the official India Code portal before relying on it, as definitions and numbering can be amended.

Why charging extra can be an unfair trade practice

The Consumer Protection Act, 2019 (which replaced the older 1986 Act) defines and prohibits certain conduct. Two concepts are central:

• Unfair trade practice, Section 2(47) of the 2019 Act covers practices that adopt unfair or deceptive methods to promote sale, including false or misleading representations about price, and offering goods or services on terms not actually intended to be honoured. Advertising one price and collecting another fits squarely within this idea.
• Misleading advertisement, Section 2(28) defines a misleading advertisement as one that falsely describes a product or service or gives a false guarantee, or conveys a representation that would constitute an unfair trade practice. A scheme advertised on terms the seller does not honour can be challenged as misleading.
• Deficiency in service, Section 2(11) covers any shortcoming or inadequacy in the quality or manner of performance that the seller is required to maintain. Collecting an undisclosed charge can be framed as both an unfair trade practice and a deficiency.

Plead all three. They are not alternatives that cancel each other out. An unfair trade practice attaches to the scheme and the advertising, a misleading advertisement attaches to the specific banner or listing, and deficiency attaches to how the transaction was actually performed at the counter. A commission that is not persuaded on one limb frequently grants relief on another.

What the consumer can claim

When a forum or commission finds in the consumer's favour, the reliefs it can order include:

The exact relief depends on the facts, the evidence, and the value of the dispute. The statutory menu is set out in Section 39 of the Consumer Protection Act, 2019, and it is wider than most complainants realise. A District Commission can order the price or charges paid to be returned with interest under section 39(1)(c), award compensation for loss or injury under section 39(1)(d) along with punitive damages where it thinks fit, direct the trader to discontinue the unfair trade practice and not repeat it under section 39(1)(g), order a corrective advertisement at the trader's cost to neutralise a misleading one under section 39(1)(l), award costs under section 39(1)(m), and direct the trader to cease and desist from issuing misleading advertisements under section 39(1)(n).

There is one further provision worth flagging in a scheme case, because it changes the arithmetic entirely. Section 39(1)(k) allows the Commission to order payment of a sum where loss or injury has been suffered by a large number of consumers who cannot conveniently be identified, and the proviso fixes a floor of not less than twenty-five per cent of the value of the defective goods sold or service provided to those consumers. A hidden charge applied uniformly across a promotional scheme is, by definition, a mass wrong. Where the same charge was collected from hundreds of customers, this is the clause to plead.

On compensation for harassment and mental agony, the leading authority remains the Supreme Court's decision in Lucknow Development Authority v. M.K. Gupta (5 November 1993), which confirmed that a consumer commission can award compensation for harassment, mental agony and oppression, while cautioning that such a finding must rest on material and convincing circumstances and should not be recorded lightly. Translated into practical drafting, that means you should not simply assert distress. Say what you actually lost: the trips to the store, the hours on a helpline, the delayed use of the product, the money blocked.

Where and how to file a consumer complaint in India

Under the 2019 Act, consumer disputes are decided by a three-tier system. The forum you approach depends on the value of the goods or services paid as consideration.

Pecuniary limits were revised by Government notification and may be updated again. Confirm the current threshold before filing.

The detail behind that table is worth understanding, because people get it wrong. Section 34(1) of the Act as enacted set the District Commission limit at one crore rupees, but it contains a proviso allowing the Central Government to prescribe a different value. The Government did exactly that: the Consumer Protection (Jurisdiction of the District Commission, the State Commission and the National Commission) Rules, 2021, notified as G.S.R. 912(E) on 30 December 2021, fix the limits at rules 3 to 5 as fifty lakh rupees, above fifty lakh up to two crore, and above two crore respectively. Note also what the threshold is measured by: the value of the goods or services paid as consideration, not the compensation you claim. For a retail exchange dispute that will almost always be the District Commission.

Territorial jurisdiction is governed by section 34(2), and it is deliberately consumer friendly. A complaint can be instituted where the opposite party ordinarily resides, carries on business, has a branch office or personally works for gain; or where the cause of action wholly or in part arises; or, importantly, where the complainant resides or personally works for gain. That last limb means a Bengaluru resident who bought from a national chain does not have to travel to the retailer's head office city.

Filing the complaint, step by step

Practical steps for a small exchange-offer dispute (which will usually go to the District Commission):

1. Freeze the evidence the same day. Screenshot the scheme page, banner, app listing or pamphlet before it is taken down, and capture the date and URL in the same image. Save the bill, the payment confirmation and every chat or email.
2. Ask the store, in writing, for a breakdown. A short email or WhatsApp message asking the retailer to explain each line on the invoice and identify where the extra charge was disclosed does two jobs. It may get you a refund, and the reply (or the silence) becomes your best piece of evidence.
3. Log a National Consumer Helpline grievance. Call 1915 or use the National Consumer Helpline. It is free, it generates a docket number, and many national brands settle at this stage rather than have a complaint escalate.
4. Send a formal notice. A one-page demand letter setting out the advertised terms, the amount actually collected, the sections relied on and a fourteen-day deadline is usually enough. Send it by email and by registered post or courier, and keep the delivery proof.
5. Identify the correct opposite parties. Name the store entity that issued the bill, and where the scheme was run or advertised by the brand or the marketplace, name that entity too. A complaint against only the shop can fail if the scheme terms were the brand's.
6. Work out the forum. Value of consideration paid decides the tier under section 34(1) read with the 2021 Rules; section 34(2) decides the place. For most exchange disputes, this is the District Commission where you live.
7. Draft the complaint. It should contain the parties, the facts in dated sequence, the specific sub-clauses of section 2(47) and section 2(28) and section 2(11) relied on, the reliefs sought under section 39, and a verification. Attach an affidavit, because under section 38(6) the complaint is heard on affidavit and documentary evidence.
8. File electronically on E-Jagriti. Complaints are filed and tracked through the Ministry of Consumer Affairs platform at e-jagriti.gov.in, the successor to the older e-Daakhil portal. Physical filing at the Commission's registry with the prescribed fee remains available. Section 35(1) expressly permits electronic filing and section 35(2) requires the prescribed fee.
9. Watch the limitation. Section 69 bars a complaint filed more than two years after the cause of action arose, unless the Commission is satisfied there was sufficient cause and records its reasons for condoning the delay. Do not rely on condonation.
10. Decide about mediation. At the first hearing after admission the Commission may, under section 37, ask the parties whether they consent to mediation. In a small refund dispute, mediation often produces a full refund plus a token amount within weeks instead of months.
11. Attend, or seek video conferencing. Section 38(6) allows the Commission to permit hearing or examination through video conferencing on sufficient cause. Say so in your application rather than assuming.
12. If you lose, appeal within forty-five days. Section 41 gives a right of appeal to the State Commission on facts or law within forty-five days, with a proviso that a party ordered to pay must first deposit fifty per cent of that amount.

You do not always need a lawyer for small-value matters, but legal help is useful where the retailer disputes the facts or the amount is significant.

Costs and timelines, realistically

Consumer litigation is the cheapest formal forum in India, and that is the point of it. The figures below are indicative ranges for a straightforward District Commission complaint in a metro such as Bengaluru, and they will vary by state, by counsel and by how hard the retailer fights. Court fee slabs are prescribed by rules that change from time to time, so confirm the current fee on E-Jagriti before you pay.

Read those two tables together and the strategy becomes obvious. For a dispute over a few thousand rupees, the notice stage and the helpline stage are where you win economically. The complaint is the credible threat that makes the notice work, and it is worth filing, but nobody should spend forty thousand rupees to recover four thousand without understanding that trade-off first.

Evidence that wins exchange-offer disputes

The single most important factor is proof of what was advertised. A commission can only hold a seller to terms the consumer can show were promised. So preserve:

• The original scheme advertisement (dated, if possible)
• The final bill showing the higher amount charged
• Any verbal assurance reduced to writing (email or WhatsApp)
• Comparison of the advertised price versus the collected price

Two additions make a real difference. First, capture the terms and conditions page that the advertisement linked to, not just the headline banner. Retailers routinely defend on the footing that the extra charge was disclosed in the fine print; if you have the fine print as it stood on the day, you can show that it was not. Second, if the charge was collected in cash or added at the counter, ask a companion to be present and record what the counter staff said, or send yourself a contemporaneous message describing it. A dated message written on the spot carries far more weight than a recollection reconstructed six months later in an affidavit.

The mistakes people actually make

• Paying first and arguing later without a note. Paying under protest is fine, but write "paid under protest, disputed excess of Rs X" on your copy of the bill or in an email sent the same evening. Silent payment invites the argument that you accepted the revised terms.
• Not saving the advertisement. Scheme pages are edited or deleted within days. This is the most common reason a genuinely good complaint fails.
• Suing the wrong entity. Naming a brand when the bill was issued by a franchisee, or naming a franchisee when the scheme was the brand's, wastes months. Read the invoice: the seller's legal name and GST number are on it.
• Treating the two-year limitation as flexible. Section 69 is a bar on admission, not a soft guideline. Condonation requires you to prove sufficient cause and the Commission to record reasons.
• Inflating the compensation claim. A claim for Rs 5 lakh in mental agony on a Rs 3,000 overcharge invites scepticism and can push you into the wrong pecuniary tier of thinking. Ask for the refund, interest, a proportionate compensation figure and costs.
• Pleading only "deficiency in service". A pricing wrong is primarily an unfair trade practice. Complaints that never mention section 2(47) give the Commission less to work with.
• Ignoring the helpline and the notice stage. Many national retailers have escalation desks that refund quickly once a docket number exists. Going straight to a complaint costs you time you did not need to spend.
• Missing the appeal deposit. A trader who loses and wants to appeal must deposit fifty per cent of the awarded amount under the second proviso to section 41. Consumers who do not know this are sometimes talked into a poor settlement by an opponent bluffing about a costless appeal.

What the retailer will argue, and how to meet it

Expect four defences, and prepare for each in the complaint itself rather than in rejoinder.

• "The charge was disclosed in the terms and conditions." Meet it with the dated capture of the terms page and with section 2(28)(iv), which makes deliberate concealment of important information a misleading advertisement, and section 2(11)(ii), which makes deliberate withholding of relevant information a deficiency.
• "The customer agreed and paid voluntarily." Meet it with the protest note, the contemporaneous message, and the point that consent obtained by non-disclosure is not informed consent. Section 2(9)(ii) recognises a right to be informed about price precisely so that a counter-side agreement cannot cure a concealed charge.
• "It is a statutory levy, tax or third-party fee." Ask for the line item, the rate and the authority for it. A genuine statutory levy will appear on the invoice with a rate and a legal basis; a made-up one will not.
• "The scheme was subject to change without notice." A right to change a scheme prospectively is not a right to change the price of a transaction already induced by the advertised terms. Point to section 2(47)(ii), which targets exactly the practice of advertising a bargain price the seller does not intend to honour.

Set out side by side, the four defences and the answer to each look like this.

A practitioner's note

In practice the fight in these matters is almost never about the law, which is clear enough on the face of section 2(47). It is about whether the consumer can produce the advertisement as it stood on the day of purchase. Retailers do not usually deny that a charge was collected; they say it was always part of the scheme and point to a terms page that reads differently today from how it read then. The complaints that succeed are the ones where somebody took thirty seconds to screenshot the offer before walking to the counter, and the complaints that collapse are the ones where the client is certain about what the banner said and has nothing to show for it. The second thing worth saying is that the notice stage is undervalued. A short, section-specific letter that names section 2(47)(iii)(a) and section 39 and attaches the screenshot resolves a large share of these disputes without a single hearing, because the retailer's legal team can see immediately that the file is a losing one. Litigation is the fallback, not the plan.

How this protects ordinary shoppers and honest businesses

This principle is not anti-business. It protects honest retailers too, because it sets a level field: a shop that advertises a scheme and honours it is not undercut by competitors who lure customers with attractive offers and then inflate the bill at the counter. Transparency in pricing is the rule the law enforces.

For consumers, the takeaway is empowering: you are entitled to the exact deal advertised. A "convenience charge", "handling fee" or "scheme adjustment" that appears for the first time at billing, and was never disclosed, is exactly the kind of conduct consumer commissions scrutinise.
