An online marketplace dispute is usually resolved through the order’s marketplace process first. If an item never arrives, arrives damaged, or doesn’t match the listing, save the evidence, contact the seller through the platform, and request a specific remedy. If that fails, escalate through the marketplace and consider whether your payment method provides a separate dispute process.

The payment method matters. A U.S. credit-card billing dispute has a written 60-day deadline under federal law. Debit cards, prepaid cards, bank transfers, and payment apps follow different rules and shouldn’t be treated like credit-card claims.

This is general U.S. consumer information, not legal advice.

The right route depends on the problem

Problem First route Deadline or limit to watch
The order never arrived Marketplace order-help or item-not-received process The marketplace’s delivery and claim deadline
The item is damaged or not as described Marketplace return or case process The platform’s eligibility rules and return window
A credit-card statement includes an incorrect charge Written dispute to the credit-card issuer Generally 60 days after the first statement showing the error was sent
A debit, prepaid, bank, or payment-app transaction is disputed The financial institution or payment provider The provider’s separate rules and notification period
You simply changed your mind Seller’s posted return policy The return period, exclusions, and possible shipping conditions

A seller’s return policy may control a change-of-mind return, but it doesn’t necessarily replace a marketplace’s protection for non-delivery or an item that materially differs from the listing. Likewise, opening a marketplace case isn’t the same as disputing a credit-card billing error.

What to save before opening a case

Collect evidence before the listing changes or messages disappear. Keep the original files and make a dated folder for the order.

Useful records include:

Save copies of online forms and chats. The Federal Trade Commission’s guidance on resolving problems with a business recommends keeping notes about your attempts to resolve a complaint and saving what you submit online.

Don’t edit screenshots in a way that removes dates, names, or context. If you redact personal information, keep an unedited copy for your own records.

Contact the seller through the marketplace

Use the platform’s built-in message or order-help system whenever possible. That creates a record connected to the transaction and makes it easier for the marketplace to review the conversation.

Be specific about three things:

  1. What went wrong
  2. What evidence supports your account
  3. What resolution you want

For example:

Hello, I’m contacting you about order #[order number]. The listing described the item as [description], but the item I received on [date] was [specific problem]. I’ve attached photos of [problem] and a copy of the listing. Please provide a [full refund, replacement, or return solution] through the marketplace order page. Thank you.

For an item that never arrived:

Hello, I’m contacting you about order #[order number]. The estimated delivery date was [date], and the tracking record currently shows [status]. I have not received the package. Please confirm the shipment status or process a refund through the marketplace.

Stay calm and factual. Don’t threaten the seller, accuse them of fraud without evidence, or move the conversation to an unprotected payment method. Don’t send a full card number, account password, or Social Security number in marketplace messages.

Opening a marketplace case

If the seller doesn’t resolve the problem, use the case, return, or item-not-received link attached to the order. Upload the strongest evidence first and explain the timeline in plain language.

A good case summary is short:

Read the platform’s instructions carefully. Some systems require you to contact the seller before opening a formal case. Others separate return requests, item-not-received claims, and payment disputes. Don’t assume that a rule from one marketplace applies to another.

Amazon A-to-z claims

For an Amazon order, start in the order’s help or return area and follow the claim instructions shown for that transaction. If the process asks you to contact the seller first, keep that contact inside Amazon and save the response.

For an A-to-z claim, submit:

Amazon’s workflow and response deadlines can depend on the order and claim type. Use the deadline in the claim notice or account page rather than relying on an outside guide that gives one fixed response period.

eBay disputes

eBay uses different processes for an item that didn’t arrive, an item that is not as described, a return, and a payment dispute. Review the eBay Money Back Guarantee policy for the transaction’s current eligibility and deadline.

A seller’s normal return window and eBay’s Money Back Guarantee are related but not identical. The policy includes separate timing rules tied to the estimated or actual delivery date and, in some situations, the seller’s return period.

Use the order page to open the appropriate request. Include the listing, tracking record, photos, and messages. If the seller says tracking proves delivery, compare the delivery details with the address on the order and explain any mismatch.

A bank or card-company payment dispute is a separate process. eBay’s payment-dispute guidance explains that these disputes are handled through a bank, card provider, PayPal, or another payment institution. Follow the marketplace process first when it is available, but don’t ignore a separate payment-provider deadline.

Etsy cases

Etsy generally expects a buyer to send a “Help with order” request before opening a case. Etsy’s case instructions say that eligibility can depend on the order, location, currency, and other details. They also identify waiting periods, including seven days after purchase and 48 hours after the help request.

When you open the case, provide the listing, order details, photos, tracking, and messages. Etsy’s guidance for resolving a buyer’s case says the seller may need to provide proof of shipping to the address on the Etsy receipt. For an item that doesn’t match the listing, describe the specific difference rather than simply saying it was disappointing.

Etsy may have purchase-protection limits and eligibility requirements. Don’t assume that every order qualifies or that the same remedy applies to every seller and product.

Shopify stores, Poshmark, Mercari, and Walmart

A Shopify-powered store may be an independent merchant rather than a single marketplace with one universal buyer guarantee. Check the store’s receipt, contact information, return policy, and order-help process. If the merchant does not respond, use the payment provider’s dispute process if your transaction qualifies.

For Poshmark, Mercari, Walmart, and other marketplaces, open the case from the order page and use the policy for that specific transaction. Avoid relying on online claims that one platform is always “seller-favored” or that a particular evidence package guarantees a win. Individual decisions depend on the listing, messages, tracking, condition, and platform rules.

Credit-card disputes: protect the 60-day deadline

If your credit-card statement includes a charge for goods you never received or another qualifying billing error, federal credit-card protections may provide a separate route.

The FTC’s guidance on billing errors says you generally must dispute the error in writing within 60 days after the first statement containing the error was sent to you. A phone call or marketplace complaint alone may not preserve the same protection, so follow up with a written notice using the billing-dispute address and instructions provided by your card issuer.

Include:

Keep a copy of the letter and proof that you sent it. Don’t send original documents.

For a qualifying dispute, the FTC says the issuer must acknowledge the dispute in writing within 30 days unless the problem has already been resolved. The issuer must generally resolve it within two billing cycles, and no more than 90 days, after receiving the letter. During the investigation, you don’t have to pay the disputed amount or related finance and other charges, but you should continue paying amounts that aren’t disputed.

Some card issuers may extend the 60-day period when a shipment is delayed. Ask the issuer if that situation applies; don’t assume an extension exists.

A disagreement with a seller’s preference-based return policy isn’t automatically a credit-card billing error. Explain the facts to the issuer and ask which dispute category and documentation apply.

Debit cards, prepaid cards, bank transfers, and payment apps

The credit-card rules above don’t automatically apply to:

Contact the provider promptly and ask about its process for non-delivery, unauthorized transactions, duplicate charges, or merchandise disputes. The provider may request different documents, and the deadline may run from the transaction date, the statement date, or another event.

If you paid through a marketplace wallet or payment app, keep the marketplace case number and tell the provider that you are also seeking a resolution through the platform. If one side refunds you, update the other promptly so the records do not suggest that you are seeking duplicate reimbursement.

If you were billed for something you never received

First check the order status, partial shipments, household purchases, and any temporary authorization on the account. If the charge is final and the goods were not delivered:

  1. Save the order confirmation and statement showing the charge.
  2. Check the carrier record and estimated delivery date.
  3. Contact the seller through the marketplace.
  4. Open an item-not-received case before the platform deadline.
  5. If you paid by credit card and the 60-day period is approaching, send the written billing dispute without waiting for the marketplace case to finish.
  6. Follow up with the carrier or payment provider if requested.

If an unsolicited package arrives, photograph the label and contents and check whether someone in your household placed the order. If your account or card shows a related charge, use the marketplace and payment-provider routes above. Don’t provide payment or sensitive account information to a sender through an unsolicited message.

What to do when tracking says “delivered”

A delivery scan is evidence, but it may not answer every question. Compare the scan with:

Tell the seller and marketplace exactly what conflicts with the record. For example, “The tracking says delivered to a location that is not the address on my order” is more useful than “The carrier is lying.”

Check nearby delivery locations and ask household members or building staff before escalating, but don’t let those checks cause you to miss a platform or card-provider deadline.

Escalation when the first case fails

If the seller or marketplace denies the claim:

  1. Save the decision, case number, and stated reason.
  2. Check whether an appeal link or review period is available.
  3. Submit a focused appeal addressing the exact reason for denial.
  4. Add new evidence rather than repeating the original complaint.
  5. If the payment method qualifies, contact the card issuer or payment provider separately.
  6. Keep a record of every date, name, and reference number.

If you believe the conduct involves a scam or illegal business practice, you can report it through the FTC’s contact and fraud-reporting information. A report is not a substitute for opening the marketplace or payment dispute that may recover your money.

For a substantial loss, small claims court may be an option if the business and transaction are identifiable. Claim limits and procedures vary by state; the FTC notes that some states set limits as high as $25,000. Check the court rules in the state connected to the transaction before filing, especially if the seller is outside the United States.

Common mistakes that weaken a marketplace claim

The strongest claim is usually organized, specific, and supported by records that connect the problem to the order.

Questions buyers often ask

Should I contact the seller or my card issuer first?

Start with the marketplace order process and contact the seller through the platform. However, if a credit-card billing-dispute deadline is approaching, protect that deadline by sending the issuer a written dispute rather than waiting for the seller or marketplace to respond.

Can I open a marketplace case and a credit-card dispute?

They are separate processes, so both may be available. Give each party accurate information, keep the case numbers, and report any refund or reversal so you don’t seek payment twice.

Does a seller’s “no returns” policy end my options?

Not necessarily. A no-returns policy may affect a change-of-mind return, but non-delivery, damage, misdescription, unauthorized charges, and credit-card billing errors can involve different rules. Review the marketplace policy and payment method separately.

What if I paid with a debit card?

Contact the debit-card issuer promptly and ask about its merchandise or non-delivery dispute process. The federal 60-day credit-card billing-error procedure shouldn’t be assumed to apply to a debit transaction.

What evidence is most useful?

The order record, listing screenshots, tracking, photos of the item and packaging, and platform messages usually establish the basic timeline. Label each file with the date and explain how it supports your requested remedy.
