If you bought a defective product in the United States, stop using it if it may be unsafe, preserve the item and your records, and complain to the seller in writing. State the defect, attach evidence, and ask for a specific remedy: refund, replacement, or repair.

Don't assume a store's ordinary return deadline ends every possible claim. A retailer's return policy, marketplace process, written warranty, state warranty law, and credit-card billing-dispute rules are separate routes with different conditions and deadlines.

File the complaint in this order

  1. Stop using the item if it could cause harm. Do not throw it away, alter it, or attempt a repair before documenting the problem.
  2. Save the evidence. Keep the receipt, order details, photos, video, serial number, packaging, listing, and all messages.
  3. Check the applicable terms. Review the retailer's return policy, marketplace tools, and any written warranty.
  4. Contact the seller in writing. Describe the defect and clearly request a refund, replacement, or repair.
  5. Return the item only through verified instructions. Keep photos of the package, tracking, and proof of delivery.
  6. Escalate before key deadlines expire. Use the marketplace process, warranty claim, or payment-provider procedure where appropriate.
  7. Use a consumer agency or small claims court if needed. Those options depend on the state and facts of the dispute.

Preserve the product and build a record

Create a short timeline while the details are fresh. Record the purchase date, delivery date, date you noticed the problem, each contact with the seller, and any return shipment.

Save:

Keep the item, accessories, packaging, and labels until the dispute is resolved. If it presents a fire, electrical, chemical, or other safety risk, stop using it and store it safely. Do not keep testing a potentially dangerous item just to create more evidence.

The Federal Trade Commission's guidance on resolving problems with a business recommends being clear about the problem and the result you want. Save chat transcripts or screenshots before leaving a support session.

Know which rule controls the problem

The fastest route is often the retailer's return process, but that process is not the same as a warranty claim or a credit-card billing dispute.

Rule or process What it usually controls
Retailer's return policy Voluntary returns, exchanges, and store refunds
Marketplace process A platform's procedure for qualifying orders and sellers
Written warranty Repair, replacement, or another remedy promised in warranty terms
State warranty law Possible rights when goods fail to work as reasonably expected
Credit-card billing dispute A procedure for certain covered billing errors, with its own deadline

Many stores set return periods such as 30 or 90 days, according to the FTC. That does not create a universal federal deadline for defective goods. A policy for a change-of-mind return may not answer whether a warranty claim is available.

Also identify who sold the item. The retailer, marketplace seller, manufacturer, and payment processor may be different businesses. The name on the order page or receipt helps determine where to start.

Send a written defective-item complaint

Use the seller's return portal, account messaging system, email address, or support form. Written communication gives you a record of what you reported and what remedy you requested.

Include:

Ask for one primary outcome. For example, request "a full refund to the original payment method" instead of saying only that you are dissatisfied. If you would accept a replacement or repair, say that separately.

Complaint email template

Subject: Defective [item] - order [number] - request for [refund, replacement, or repair]

Hello [seller or support team],

I purchased [item name and model] on [date]. My order or invoice number is [number].

The item is defective because [brief factual description]. I first noticed the problem on [date]. It [does not work, arrived damaged, overheats, leaks, or does not match the listing].

I am requesting [a full refund to the original payment method, a replacement, or a repair]. I have attached [photos, video, receipt, listing screenshot, and other evidence].

Please confirm the next step and provide any return instructions by [date]. If a return is required, please confirm the return address, label, and how return shipping will be handled.

Thank you,

[Your name]
[Phone or email]
[Shipping address, if needed]

Keep the complaint factual. Avoid unsupported accusations or legal threats that can distract from the defect, evidence, and requested remedy.

Return the product carefully

Do not send the item to an address from an unrelated email, text, or social-media message. Use the return instructions in your order account or from the seller's verified support channel.

Before shipping:

  1. Get a return label or written instructions.
  2. Confirm whether the seller wants accessories, manuals, or original packaging.
  3. Photograph the item and its condition before packing.
  4. Photograph the sealed package and shipping label.
  5. Use tracking and keep the shipping receipt.
  6. Save proof that the package was delivered.
  7. Ask when and how the refund, replacement, or repair decision will be processed.

If the seller tells you to dispose of the item, keep that instruction in writing. A carrier scan or delivery confirmation proves shipment or delivery; it does not by itself prove that a refund has been approved.

If the seller asks you to pay return shipping, accept a repair, or pay a restocking fee, ask it to identify the return-policy or warranty term it relies on. Whether that condition applies can depend on the transaction, the defect, and state law.

Use the marketplace process for marketplace orders

Marketplace rules can vary by country, seller, item category, and order. Use the help options and deadlines shown for the specific transaction in your account.

Amazon

Start in Your Orders and select the option that best describes the defect. For a third-party seller, contact the seller through the order page and keep the messages in Amazon when possible.

If the seller does not resolve the issue, look for the A-to-z Guarantee or other available claim option in that order. Eligibility and filing windows can vary. Amazon's A-to-z Guarantee guidance is tied to a non-U.S. marketplace, so do not use a deadline from that page for a U.S. order. Use the help page connected to your own order.

eBay

Open the transaction in Purchase History and use the return or case option available there. Select the reason that accurately describes the problem, such as defective or not as described, and upload relevant photos, listing screenshots, and messages.

Check the deadline shown for that transaction. Do not close an open case merely because the seller promises a refund unless the refund has been issued or eBay directs you to close it.

Walmart

Open the order details in the Walmart website or app and check whether Walmart sold the item or whether it came from a Walmart Marketplace seller. The available return path can differ.

For an in-store purchase, use the current return instructions for that purchase. If you do not have a receipt, ask whether the store can use another record, such as an order number or payment record.

SHEIN and Temu

Use the order page in the app or website, select the defective or damaged-item reason that fits, and upload clear photos. Save screenshots of the request and any instructions about return shipping.

Do not assume a deadline mentioned online applies to every order. Terms can vary by country and account. Temu's return and refund policy includes country-specific terms, so use the version linked from your U.S. account.

Warranty rights can outlast a store return window

A store's return deadline is not automatically the deadline for every warranty claim or lawsuit. Track each date separately:

Implied warranties

State law may provide an implied warranty that goods sold by a business are fit for their ordinary purpose. A product that fails during normal use may raise an implied-warranty issue even after a voluntary return window has closed.

The details vary by state. State law can affect the scope of the warranty, whether it can be disclaimed, notice requirements, and the deadline for filing a legal claim. "Final sale" language may limit ordinary returns, but it does not by itself answer every defective-goods or warranty question.

Written warranties

A manufacturer or retailer may offer a written warranty that provides repair, replacement, or another remedy. Read the warranty for:

The FTC's guide to federal warranty law explains federal requirements related to written consumer-product warranties. The Magnuson-Moss Warranty Act does not automatically require a cash refund for every defective item; the available remedy depends on the warranty terms and applicable law.

When a credit-card billing dispute may help

A credit-card billing dispute is not a general way to bypass a return policy. Under the Fair Credit Billing Act, the billing-error process can apply to certain problems, including charges for goods you did not accept or goods that were not delivered as agreed.

If your situation may qualify, send written notice to the card issuer's billing-dispute address so it arrives within 60 days after the first statement containing the error was sent. Include your account information, the disputed amount, a description of the problem, and copies of your order record, seller complaint, evidence, and return tracking.

The FTC says the issuer generally must acknowledge the complaint within 30 days unless it has already resolved the matter, and must resolve it within 90 days. Review the FTC's credit-card dispute guidance and your issuer's instructions before filing.

Use the most accurate reason for the dispute. An authorized purchase that turned out to be defective is not the same as an unauthorized transaction. Debit cards, prepaid cards, bank transfers, and other payment methods can have different protections and provider procedures, so contact the provider promptly.

Escalate if the seller refuses or stops responding

Work through the available channels without losing track of their deadlines.

  1. Send one written follow-up. Refer to the original complaint, attach the key evidence, and ask for a written decision.
  2. Request review by a supervisor or warranty specialist. Ask the business to consider the matter as a defective-goods or warranty claim, not only as a routine return.
  3. Open the marketplace case. Use the official order page or app, not a link sent by an unknown person.
  4. Contact the manufacturer. This can be useful when the written warranty lasts longer than the retailer's return period.
  5. Ask the payment provider about a dispute. Follow its procedure and deadline.
  6. File a consumer complaint. Your state attorney general, a local consumer-protection office, or the FTC may accept reports. A complaint can document a pattern of conduct, but it usually does not guarantee an individual refund.
  7. Consider small claims court. Dollar limits, filing fees, service requirements, and venue rules vary by state. The FTC notes that some states allow claims as high as $25,000. Check any arbitration clause before filing.

If the product caused an injury or presents a serious safety risk, preserve the item and records separately from the refund dispute. A customer-service decision does not resolve every potential safety or product-liability issue.

Common questions

Can a store refuse a return after its stated deadline?

It may refuse a voluntary return under its policy, especially for a change-of-mind purchase. If the item is defective, ask the seller to review it under its warranty or defective-goods process and keep the response in writing.

What if I do not have a receipt?

Provide an order confirmation, account history, payment record, gift receipt, serial number, or other record that identifies the purchase. Ask the retailer what alternative proof it will accept.

Is defective the same as not as described?

Not always. A defective item may fail to work or be unsafe. An item that is not as described may function but differ from the listing, model, material, size, or promised feature. Choose the reason that matches the evidence.

Should I accept a replacement instead of a refund?

Choose the remedy that addresses the problem. If the issue suggests a safety concern or repeated quality problem, explain why a replacement is not suitable and request a refund. The seller's policy, warranty, payment method, and state law can affect what remedy is available.

Start by saving the order page, photographing the defect, and sending one written request that identifies the item, explains the problem, and states the remedy you want.
