Received an online purchase that arrived broken, stopped working, or didn't match the listing? A usable dispute connects four facts: what you ordered, what the seller promised, what went wrong, and the remedy you want. File that explanation through the marketplace or payment channel that actually controls the order, and do it before that channel's deadline.

There isn't one universal U.S. defective-item dispute rule. Marketplace policy, payment method, the seller's terms, and state law can all matter. A platform decision also isn't a court ruling on warranty rights. The steps below are practical consumer information, not legal advice.

Identify the problem correctly

Use the category that matches what happened. Calling a purchase you actually made "fraud" or "unauthorized" can send the claim into the wrong process.

Problem How to describe it
Defective item The product fails an advertised or essential function, arrived broken, or has a safety-related fault.
Not as described The condition, model, size, material, authenticity, quantity, or specifications differ from the listing.
Shipping damage The product or packaging shows damage that appears to have happened during delivery.
Missing or wrong item The order was not delivered, contains the wrong product, or is missing parts.
Change of mind The product works and matches the listing, but you no longer want it. That is usually a return-policy issue, not a defect claim.
Unauthorized transaction You did not make or approve the purchase. Use the payment provider's fraud channel instead.

If more than one problem applies, separate them. "The box was crushed in transit, the blender jar is cracked, and the motor does not start" gives a reviewer something to check. "Item is bad" does not.

Gather evidence before you open a case

Save or screenshot the listing, including photos, condition, specifications, quantity, and any warranty language. Keep the order confirmation, receipt, order number, payment amount, estimated delivery date, tracking history, return and refund terms, and every message with the seller or platform.

The FTC's online shopping guidance recommends reviewing delivery, return, and refund policies and keeping records. If a seller did not promise a shipping time, the FTC says the seller generally must ship within 30 days after receiving the name, address, and payment needed to process the order. That is a shipping rule, not a deadline for reporting a defective product.

Photograph the whole product, the defect from more than one angle, any serial or model number, the included parts, and the shipping box, label, padding, and visible damage. A shot of the item next to the listing helps when the problem is a mismatch. A video of the failure can help, but an unboxing video is not required for every claim and does not prove every part of the dispute by itself. Keep original files rather than relying only on edited or compressed copies.

Stop using a product that may be unsafe. Don't repair or modify it before the seller or platform tells you what to do, unless that is necessary to prevent further damage.

Check who actually controls the dispute

Some marketplace operators handle returns and refunds themselves. Others leave payments, delivery, and refunds to the buyer and seller. The FTC's marketplace guidance recommends checking the seller's description and contact information and understanding how involved the marketplace is.

Your first route may be the marketplace's order-resolution system, the seller's return or warranty process, PayPal Purchase Protection, a credit-card billing dispute, or a debit-card or bank process. A marketplace deadline, a PayPal deadline, and a card issuer's deadline are not interchangeable.

Send one concise message through the marketplace's own messaging system: state the defect, attach a small set of useful evidence, and ask for a specific remedy. Keep the conversation on-platform when you can. If the seller promises a replacement or refund, save that promise and don't close an open case until the remedy is actually completed, or until you understand the platform's rules for closing it.

Look up the deadline on the order page, case screen, payment account, or written policy. Screenshot it. Waiting for the seller to reply can burn the only window you have.

How to write a clear defective-item explanation

Put the facts a reviewer can verify first.

  1. Order identification: order number, product name, purchase date, and delivery date.
  2. Listing promise: quote the relevant wording instead of paraphrasing the whole listing.
  3. Observed problem: what fails, when you noticed it, and what basic test you ran.
  4. Impact: whether the product is unusable, missing an essential function, unsafe, or materially different.
  5. Evidence and remedy: the proof you attached, plus a refund, replacement, repair, or other specific outcome.

For example:

I ordered a new wireless headset under Order 123456. The listing says it has a 20-hour battery and includes two working earbuds. It arrived on March 4. The right earbud will not charge after testing it with the supplied case and cable. The packaging had no visible exterior damage. I attached photos of the earbud, a video showing the charging failure, and a screenshot of the listing. I am requesting a full refund and return instructions if the item must be sent back.

That is more useful than "The headphones are terrible" or "The seller scammed me."

Template you can adapt

Issue: Defective item or not as described

Order: [Order number], [product name], purchased on [date], delivered on [date]

I ordered this item because the listing states: "[quote the relevant description]."

The problem is: [describe the defect or mismatch precisely]. I noticed it on [date] after [brief, honest description of testing or ordinary use]. The item is [unusable, missing a key function, damaged, unsafe, or materially different from the listing].

The packaging was [intact/damaged]. I have attached [listing screenshot, photos, video, tracking information, and seller messages].

I contacted the seller through [platform] on [date]. The response was [brief summary].

I am requesting a [full refund/replacement/repair]. If a return is required, please provide the platform-approved return instructions and any required label. I have kept the item, packaging, and accessories.

Shorten it if the form has a character limit. Skip unsupported legal conclusions, threats, insults, and guesses about the seller's intentions.

Platform and payment deadlines

PayPal

For U.S. PayPal purchases, the published Purchase Protection terms say a dispute must be opened within 30 days of the delivery or fulfillment date, or within 180 days of the payment date, whichever is sooner.

Opening a dispute is not the same as escalating it to a claim. Start in the Resolution Center, provide the requested evidence, and follow the case instructions if you cannot resolve it with the seller. Eligibility and the final decision are governed by PayPal's current terms; PayPal says it may decide, in its discretion, including by automatically closing a dispute or claim. Read the instructions in your case rather than a general blog post.

If a card-issuer claim is also available, read PayPal's current terms before filing in both places. Some PayPal buyer-protection terms require you to choose one route and do not allow a double recovery.

eBay

Use the transaction-issue process connected to the order. For covered issues, the eBay Money Back Guarantee policy lists a reporting period of 30 calendar days after the estimated or actual delivery or collection date has passed. Coverage, exclusions, and the deadline shown for a particular transaction can vary, so check the order page.

If eBay decides the outcome, its policy says an appeal may be submitted within 30 calendar days of that decision. Keep return tracking and all communication in the case record.

Amazon

Amazon's A-to-z Guarantee and return procedures can vary by marketplace and country. Use the route shown in Your Orders for the specific purchase, contact the marketplace seller when instructed, and save the case history.

Don't copy a generic "90-day Amazon deadline" from an older guide. The official Amazon A-to-z information available for France includes France-specific conditions, such as a seller-contact requirement and a delivery-date condition. Those details should not be treated as U.S. terms. For a U.S. order, follow the policy and deadline displayed for that order.

AliExpress

Open the dispute from the order page while the platform still permits it. Select the reason that best matches the facts, upload the listing screenshot and defect evidence, and follow the return or refund instructions shown in the case.

Don't treat the often-repeated 15-day figure as a universal rule for every AliExpress order or country. Use the timer in your account and screenshot it. Don't close the dispute just because a seller promises to fix the problem later.

Etsy, Walmart, Shopify stores, and other marketplaces

These services do not share one deadline. A marketplace may run its own buyer-protection process, or it may send you mainly to the individual seller. Check the order page, seller terms, and payment method.

If you paid through PayPal, PayPal's own deadline may apply separately from the marketplace's return window. If you paid directly by credit card, ask the card issuer about its merchandise-dispute process right away.

Credit-card and debit-card disputes

A direct credit-card billing dispute is a separate payment route from a marketplace claim. Call the number on the back of the card or use the issuer's secure channel, and ask specifically about a purchase that was defective or materially not as described.

Follow the issuer's instructions on the reporting deadline, whether notice must be in writing, the mailing address or online form, the documents it wants, whether any temporary credit is provisional, and what happens if the merchant challenges the dispute.

Send the receipt, listing, photographs, seller correspondence, return tracking, and a short timeline. Don't describe an authorized purchase as fraud.

Debit-card protections and bank procedures can differ from credit-card billing disputes. Contact the bank promptly and ask which process applies.

When the seller blames shipping damage or misuse

Answer the allegation, not just the original complaint.

If the claim is shipping damage, show the outer box, inner packaging, shipping label, and product damage, and say whether the box looked damaged before you opened it. If the product failed inside intact packaging, say that clearly. For alleged misuse, describe the setup and ordinary test you performed, the instructions you followed, and any dated photos or video.

Be accurate about timing. "The product stopped charging after three days of ordinary use" is stronger than "dead on arrival" if it did not fail on arrival. A defect that appears after normal use can still matter; the explanation has to match what happened.

For missing parts, list exactly what the listing promised and what was absent. For authenticity concerns, describe the measurable mismatch, packaging detail, or identifying mark. Don't accuse the seller of fraud unless you have a factual basis.

Returning the item without losing the case

Don't mail the product to an unverified address or use a return method the platform won't recognize. Wait for the platform or seller to give the required instructions.

Before you ship, photograph the item, serial number, accessories, and final package. Keep a copy of the return label and receipt. Use tracking that shows delivery when the policy requires it, upload that number to the case, and hold the item and shipping records until the refund or replacement is confirmed.

Whether return shipping is covered depends on the platform's policy, seller terms, and the reason for the return. Ask for the required label instead of assuming who pays.

If a seller offers a partial refund, decide whether you are willing to keep the item. Before you accept it or close the case, check whether that action ends the dispute or blocks a later claim.

Mistakes that weaken defective-item disputes

Vague wording ("broken," "poor quality") without a described failure is a common reason claims stall. So is failing to save the listing before it changes, calling a later failure "defective on arrival," or uploading photos that don't show the model or defect. Reviewers also need the order number, delivery date, and a specific remedy.

Other problems that undercut a case: labeling an authorized purchase as fraud, sending the item back without tracking or approved instructions, moving the conversation off-platform, waiting on the seller until the platform deadline expires, and closing a case before the promised refund or replacement arrives. Filing overlapping PayPal and card claims can also create trouble if the payment terms require you to pick one route.

No video, single photograph, or carefully worded sentence guarantees a refund. What helps is a consistent record a reviewer can verify.

If the first decision is unfavorable

Read the decision reason before you appeal. Address the stated problem instead of pasting the original message again. Add any missing listing screenshot, delivery record, test result, or return tracking.

Use the platform's appeal route when one exists. For PayPal, follow the dispute-to-claim process and its time limits. For a direct card purchase, ask the issuer how to respond to the merchant's evidence.

If the seller appears to be running a broader deceptive practice, keep the records and consider reporting the conduct to the appropriate consumer-protection agency. That report is separate from a request for your individual refund. For a high-value purchase, an injury, or a serious safety issue, professional legal or safety advice may be appropriate.

Final checklist

Before you submit, confirm that you have:

Open the order page now, save the current policy deadline, and submit a factual explanation with the strongest evidence first.
