A disputed online purchase rarely gets resolved by one angry email. The stronger path is narrower: save the listing and proof of payment, name the exact problem, ask the seller or marketplace for one remedy, and use the payment provider's deadline before it expires.

The right channel depends on the payment method and the facts. A package that never arrived is not the same as a stranger using your card, and a marketplace return case is not the same as a credit card billing dispute. The following applies to U.S. consumers; platform terms and state rules can change the details.

Start by identifying the problem

Problem First step Evidence to save
The order never arrived Contact the seller and marketplace, then the payment provider if needed Promised ship date, tracking history, delivery address, and messages
The item is fake, damaged, or not as described Open a return or item-not-as-described case Listing, photos, packaging, serial numbers, and an authenticity report if available
You received the wrong item or quantity Ask for a replacement or refund in writing Order confirmation, packing slip, photographs, and the amount charged
You were charged twice or for the wrong amount Contact the seller and your card issuer or bank Statement, receipts, invoices, and both transaction records
You did not authorize the transaction Contact the bank, card issuer, or payment app immediately Account alerts, transaction details, and any evidence of account takeover
You changed your mind Check the seller's return policy Return terms, dates, and any restocking or shipping disclosures

Do not describe an authorized purchase as "unauthorized" because the seller failed to deliver. Payment providers treat those claims differently, and the wrong reason can weaken an otherwise good case.

Step 1: Preserve your evidence

Make a copy of the transaction file before you contact anyone. You are creating a record that a reviewer can verify without asking you for missing pieces.

Keep the original packaging and item until the seller, platform, or payment provider gives return instructions. If you send something back, use the required address and a trackable service. Save the receipt and delivery confirmation.

For a suspected counterfeit, photograph labels, serial numbers, logos, and differences between the listing and the item received. Do not make claims you cannot support, and do not discard the product before the dispute is resolved.

Step 2: Ask the seller for a specific remedy

Use the seller's official contact form or the marketplace's messaging system. State the facts in date order and request one clear remedy: a full refund, a replacement, or another solution you would actually accept.

Give the seller a reasonable response date that fits the platform's case deadline. If a phone agent makes a promise, send a follow-up message confirming what was said.

You can use this template:

On [date], I paid [amount] for [item]. The listing stated [shipping or product promise]. The problem is [brief factual description]. I am requesting [refund or replacement]. Please confirm the next step in writing by [date]. I have attached [key evidence].

Do not wait indefinitely for a response. A seller's internal promise does not extend a card issuer's dispute deadline or a marketplace's case window.

What federal shipping rules can do

For covered U.S. internet, mail, and telephone orders, the Mail, Internet, or Telephone Order Merchandise Rule generally requires a seller to ship within the time it stated. If no shipping time was given, the rule generally uses 30 days.

If the seller cannot ship on time, it generally must notify you of the delay and give you a choice to agree to a later date or cancel and get a refund. The rule addresses shipment delays. It does not automatically decide whether an item is counterfeit, defective, or sufficiently similar to its listing. It also does not replace the dispute deadlines set by your card issuer or marketplace.

Step 3: Use the marketplace's dispute process

Open the case through the official website or app, not a link sent in an unexpected email. Upload the most relevant evidence and keep the case number.

A platform decision is useful evidence, but it is not automatically binding on your bank or card issuer. Conversely, opening a card dispute does not guarantee that a marketplace will keep handling the order. Follow the rules for each process and report any refund you receive.

Step 4: Dispute the payment through the correct channel

Credit card purchases

Credit cards provide a formal federal billing-error process for certain problems, including charges for goods you never received. The FTC's consumer guidance on billing errors says to dispute the error in writing within 60 days after the first statement containing the error was sent.

Take these steps:

  1. Call the issuer promptly and ask how it wants the dispute opened.
  2. Send a written notice to the billing-inquiries address on the statement. That address may differ from the payment address.
  3. Identify the account, merchant, transaction date, amount, and precise problem.
  4. Attach copies of the order, listing, tracking, correspondence, return proof, and platform decision.
  5. Continue paying the undisputed part of the bill while the investigation is open.

For a qualifying dispute, you generally do not have to pay the disputed amount or related finance and other charges during the investigation. The issuer must acknowledge a written dispute within 30 days unless it has already resolved it, and it must generally resolve the matter within two billing cycles, with an outside limit of 90 days.

The 60-day period is tied to the statement containing the billing error, not necessarily the date you placed the order. Some issuers may be more flexible when a shipment is delayed, but do not treat that as a right. Card-network chargeback rules can also have different time limits, so act immediately rather than relying on a general number found online.

Your letter can be simple:

I am disputing a billing error of [amount] on my account. The charge from [merchant] dated [date] was for [item]. The merchandise was [not received, materially different from the description, or another accurate reason]. I contacted the merchant on [dates], but [result]. Please investigate and correct the account. Copies of my supporting records are enclosed.

Send copies, not irreplaceable originals, and keep proof that the issuer received the notice.

Debit cards and prepaid cards

The credit card billing-error rules do not automatically apply to a debit or prepaid card purchase. Contact the bank or card issuer immediately and ask for its merchant-dispute procedure. If the transaction was truly unauthorized, say so clearly and ask about the issuer's electronic-transfer error process.

For an authorized purchase that was never delivered or was misrepresented, the bank's agreement, card-network rules, and merchant or platform policy may control. Get the dispute instructions in writing and meet the earliest deadline shown.

PayPal

Open the transaction in PayPal's Resolution Center as soon as you identify the problem. Choose the reason that accurately matches the facts, upload the listing and correspondence, and follow PayPal's instructions for escalating a dispute to a claim.

PayPal's Purchase Protection eligibility and time limits depend on the transaction and the terms applicable to your account or region. Do not rely on an old blog post or a seller's statement about the deadline. If PayPal was funded by a credit card, the card issuer may have a separate process, but the two cases can interact. Tell both providers about the other case and do not keep duplicate refunds.

Apple Pay, Google Pay, and other digital wallets

A digital wallet often passes the transaction to an underlying credit card, debit card, or bank account. Check the receipt to identify that payment method. Start with the merchant or wallet support if you need help locating the transaction, then use the underlying issuer's dispute process when appropriate.

If you paid by credit card through a wallet, provide the issuer with both the wallet receipt and the card statement. If the underlying method was a debit card, follow the bank's debit-dispute procedure instead.

Bank transfers, peer-to-peer payments, and cryptocurrency

Contact the provider immediately and ask whether it can freeze, recall, or reverse the transfer. Recovery is less predictable than with a credit card, particularly when you authorized the payment after being deceived.

For an unauthorized account transaction, contact the bank or app at once, change compromised passwords, and secure the account. For a cryptocurrency payment, preserve the wallet address, transaction hash, messages, and website details. Do not pay a company that promises guaranteed crypto recovery in exchange for an upfront fee.

How to build a stronger dispute

Payment providers and marketplaces need a concise explanation they can match to records. Before submitting, check that your claim:

  1. Names the exact issue. Say "merchandise not received" or "not as described" when that is what happened. Do not use "fraud" for an ordinary return disagreement.
  2. Shows the promised and actual result. Compare the listing's words with the tracking record or product photographs.
  3. Documents your attempt to resolve it. Include dates, the seller's response, and any case number.
  4. Requests the correct amount. Dispute only the amount still owed. Update the provider if the seller issues a partial refund.
  5. Meets the deadline. A pending marketplace case does not stop a card or PayPal clock unless that provider says it does.
  6. Answers follow-up questions. An issuer may ask for a signed statement, return tracking, or proof that the merchant's response was inadequate.

A temporary credit from a card issuer is not always final. Keep the funds available until the issuer confirms the decision, because the credit can be reversed after the merchant responds.

Deadlines and timelines to track

There is no universal "online purchase dispute" deadline. Track each clock separately:

Route Clock to watch What it controls
Credit card billing error Written notice within 60 days of the statement containing the error Federal billing-error rights for qualifying disputes
Credit card investigation Acknowledgment within 30 days and resolution within two billing cycles, no more than 90 days The issuer's investigation timeline
Card-network chargeback Issuer and network rules Network processing, which may differ from the federal billing-error period
Marketplace case Deadline shown in the order, return, or dispute screen Eligibility for platform review
PayPal or wallet Terms and account-specific instructions Whether the provider accepts and reviews the case
Delayed shipment Seller's promised shipping time, or generally 30 days when no time was stated The seller's obligations under the federal shipping rule

Use a calendar reminder when you open a case. If a credit card statement deadline is approaching, send the written notice even while the seller or marketplace is still reviewing the complaint.

What to do if the claim is denied

Read the denial instead of reopening the same case repeatedly. It should identify the missing evidence, policy exclusion, or reason the provider accepted the seller's position.

Then:

  1. Ask for the decision and reason in writing if you do not already have them.
  2. Submit a focused response addressing that reason, with new evidence rather than a large unorganized file.
  3. Include delivery proof, return tracking, product comparisons, or the seller's written promise as relevant.
  4. Ask whether an appeal or reconsideration is available and note its deadline.
  5. If the payment provider mishandled a timely written credit card dispute, ask for a supervisor and preserve the correspondence.

You can report suspected fraud or a recurring deceptive practice to the FTC at ReportFraud.gov. A report creates an enforcement record, but it is not a substitute for opening a marketplace or payment dispute. For a substantial loss, check your state's attorney general and small-claims court procedures. Confirm the seller's legal name, service requirements, filing limit, venue rules, and any arbitration clause before filing.

Mistakes that can weaken a claim

For a cross-border order, the marketplace's applicable terms and your payment provider's rules may be more practical than trying to apply another country's cooling-off or warranty rules. Ask where a return must go, who pays shipping under the applicable policy, and how currency conversion will affect the amount credited.

Frequently asked questions

Is a chargeback the same as a refund?

No. A merchant or marketplace refund is voluntary or policy-based. A chargeback is a payment-provider investigation that can reverse a transaction under card-network rules or applicable law. Neither route guarantees a favorable result.

Should I contact the seller before my credit card issuer?

Contacting the seller creates a useful record and may resolve the problem quickly. It should not make you miss the credit card's written billing-error deadline. For an unauthorized transaction, contact the issuer or bank immediately rather than waiting for the seller.

Can I dispute an item just because I do not like it?

Usually, start with the seller's return policy. Do not describe buyer's remorse as non-delivery, counterfeit goods, or an unauthorized transaction. If the listing materially misrepresented the product, preserve the comparison and explain that specific difference.

What if the tracking says delivered but I never received the package?

Ask the seller and carrier for delivery details, check the address on the order, and document any misdelivery or theft report. Then use the marketplace and payment-provider process before its deadline. A tracking scan is evidence, but it may not answer whether the package was delivered to the correct address.

Can I open a PayPal case and a card dispute?

You may have separate avenues, but do not pursue duplicate recovery. Tell each provider about the other case, follow its instructions, and close or update a case when the transaction has been refunded.

This is general information, not legal advice. Start with three concrete tasks: save the listing, calendar the earliest deadline, and send one factual written request through the official seller or marketplace channel.
