Follow the payment trail first. The strongest evidence in a billing fight is usually the statement, receipt, order confirmation, or contract showing where the money went. Save that evidence, contact the bank or payment provider quickly, ask the business for a written fix when it's safe, and report suspected fraud to the right agency.

Reporting to the FTC can help regulators spot patterns, but it isn't a chargeback and it doesn't guarantee a refund. The deadline and remedy depend on the payment method, contract, and state law. The steps below are for U.S. consumers and provide practical information, not legal advice. They don't cover EU cooling-off rights or other foreign consumer laws.

Do this first

1. Stop the loss. Don't send more money to unlock a refund, pay a recovery service, or verify an account for someone who contacted you unexpectedly. If a legitimate business is involved, keep the conversation in writing instead of cutting off every channel.
2. Preserve the proof. Save receipts, statements, order confirmations, contracts, emails, texts, chat logs, screenshots, phone numbers, usernames, website addresses, and delivery records.
3. Secure exposed accounts. From a trusted device, change reused passwords, turn on multifactor authentication, and contact your bank or card issuer if you shared login details or one-time codes.
4. Contact the payment provider. Tell the bank, card issuer, gift-card company, cryptocurrency exchange, or transfer service what happened. Ask for its fraud or dispute process and write down the case number.
5. Report the conduct. Use the FTC reporting route for scams and the right financial, state, or law-enforcement channel for the business involved.

The FTC's guidance on what to do if you were scammed emphasizes contacting the payment company quickly. Recovery isn't assured, but delay can make the provider's investigation harder.

Evidence to keep

Keep one folder with:

• A timeline showing dates, amounts, names, and what each person promised
• The receipt, invoice, statement, contract, or warranty
• Screenshots showing the full website address, sender details, and cancellation terms
• Copies of complaints, dispute forms, emails, and letters
• Proof of delivery, return shipping, cancellation, or attempted resolution
• Bank, card, platform, or police case numbers
• A short statement of the remedy you want, such as a refund, correction, repair, or account closure

Don't edit screenshots or delete messages. If a device may be compromised, preserve what you can first and then secure it.

Choose the dispute route that matches how you paid

A credit-card dispute is not the same as a debit-card claim, gift-card recovery request, or cryptocurrency complaint. Use the process for the payment rail that moved the money.

There's a crucial difference between an unauthorized transaction and a payment you authorized because a scammer deceived you. Tell the provider the facts accurately. The investigation, legal protection, and recovery options can differ.

A merchant's refund policy, a card issuer's billing-error process, and a platform's buyer-protection policy are separate systems. One doesn't automatically replace the others.

Report the scam

Report the scam at ReportFraud.ftc.gov. Include:

• The scammer's phone number, email address, social-media account, or website
• The date and amount of each payment
• The payment method and financial institution involved
• What the scammer claimed or threatened
• The personal information you shared
• Any account numbers, wallet addresses, tracking numbers, or case references

The FTC's contact page directs people targeted by an illegal business practice or scam to ReportFraud.ftc.gov. Keep your original documents in case your bank, card issuer, insurer, or law-enforcement agency requests them.

If someone used your identity or sensitive personal information, use IdentityTheft.gov and contact the affected companies. Ask credit-reporting agencies about a fraud alert or security freeze when appropriate. Monitor statements and account alerts for activity you don't recognize.

Additional reporting may be useful:

• State attorney general: deceptive conduct by a business operating in your state
• State licensing regulator: professionals or licensed companies
• Consumer Financial Protection Bureau: many problems involving lenders, debt collectors, credit reporting, banks, and other covered financial companies
• Local law enforcement: threats, stolen property, or a report needed by your financial institution

A report creates a record. It doesn't by itself cancel a debt, reverse a transfer, or force a company to compensate you.

Credit-card billing disputes

The federal billing-error process has specific steps. The FTC's guide to using credit cards and disputing charges explains the process and includes a sample letter.

1. Identify the first statement date. Find the first bill that showed the disputed charge or other billing error.
2. Contact the merchant if that is safe and useful. Ask for a correction in writing, but don't wait for a merchant response if an issuer deadline is approaching.
3. Write to the card issuer. Your dispute should reach the issuer within 60 days after the first bill with the error was sent. Use the billing-dispute address shown on the statement or issuer instructions; it may differ from the address used for payments.
4. Describe the transaction precisely. Include the transaction date, amount, merchant, account identifier, and reason for the dispute. Attach copies rather than originals.
5. Keep proof. Save the letter, attachments, delivery confirmation, online submission receipt, and all issuer responses.
6. Pay the undisputed balance. A dispute doesn't automatically excuse payment of other charges on the account.
7. Track the investigation. Under the billing-error process described by the FTC, the issuer generally must acknowledge the complaint within 30 days unless it has already resolved it, and resolve the dispute within 90 days.

Your issuer may call the process a chargeback. That term describes a payment-network or issuer procedure; it isn't a promise that the charge will be reversed. Separate card-network deadlines may apply to disputes that don't fit the federal billing-error process, so contact the issuer as soon as you notice the problem.

Simple dispute-letter structure

State the facts without exaggeration:

• "I am disputing the charge of [amount] from [merchant] dated [date]."
• "The reason is [unauthorized transaction, duplicate charge, goods not received, or another specific billing error]."
• "I contacted the merchant on [date], and the response was [result]," if applicable.
• "Please investigate and correct the account. Attached are copies of [evidence]."

Don't send your full Social Security number, online-banking password, or one-time authentication code in a dispute letter.

Defective products and warranty claims

Federal warranty law is not a universal 30-day return policy. A store's return policy, the written warranty, implied-warranty rules, and state law may all affect the result.

The Magnuson-Moss Warranty Act concerns written warranties on consumer products. The FTC's Businessperson's Guide to Federal Warranty Law explains that covered written warranty terms must be disclosed clearly, and FTC rules require pre-sale availability for written warranties on consumer products priced above $15. Written warranties are generally identified as full or limited and must explain important coverage terms.

The law doesn't require every business to offer a warranty, and it doesn't guarantee an automatic refund for every defective product. Check:

• Who provided the warranty: manufacturer, retailer, or another company
• Coverage period and covered parts
• Exclusions for misuse, accidents, wear, or unauthorized repairs
• Whether the warranty covers labor, shipping, or diagnosis
• The required claim and dispute-resolution procedure
• Whether proof of purchase, a model number, or a serial number is required

Warranty enforcement steps

1. Photograph the defect and record when it appeared.
2. Locate the warranty and receipt or other purchase proof.
3. Contact the warrantor using the required method.
4. Describe the defect, prior repair attempts, and the remedy promised by the warranty.
5. Ask for the response and decision in writing.
6. Follow any required dispute-resolution program.
7. If the company refuses to follow the written terms, consider your state attorney general, a local consumer-protection office, small claims court, or qualified legal help.

Vehicle lemon laws are state-specific. There's no nationwide rule that three repairs always entitle a buyer to a refund. Check the law in the state connected to the vehicle purchase, registration, or repair before relying on a repair-count rule.

Subscription and recurring-billing disputes

Before starting a free trial or subscription, record the price after the trial, renewal frequency, cancellation method, and any minimum term. A free trial that requires a payment method can convert into a paid subscription under the disclosed terms.

To cancel:

1. Use the account or payment method identified in the subscription terms.
2. Complete every confirmation step.
3. Save the confirmation page, email, date, and cancellation reference.
4. Check later statements for another charge.
5. If billing continues, contact the merchant in writing and then the payment provider.

Uninstalling an app usually isn't the same as canceling its subscription. If you subscribed through an app store, check whether the store or the merchant controls cancellation.

Don't assume that a nationwide federal one-click cancellation rule applies to every subscription. The applicable contract, payment method, state law, and facts matter. If the terms were hidden, consent was misleading, or cancellation was obstructed, preserve screen recordings and report the conduct to the FTC. For a credit card, a post-cancellation charge may fit the billing-dispute process described above. For a debit card or bank transfer, contact the bank promptly and ask which process applies.

Debt collectors, loans, and medical bills

The Fair Debt Collection Practices Act can protect consumers from abusive, deceptive, or unfair conduct by covered third-party debt collectors. It doesn't automatically apply to an original creditor, every business debt, or every person seeking payment.

Before paying a debt:

• Verify the collector's name, company, mailing address, creditor, and amount claimed.
• Compare the demand with your records.
• Ask for written information about the debt.
• Dispute inaccurate information in writing and keep a copy.
• Record dates, times, phone numbers, and statements that seem threatening or misleading.
• Don't ignore court papers. A complaint to an agency doesn't replace a court response deadline.

For a medical bill, request an itemized statement and compare it with your insurer's explanation of benefits. Ask the provider to correct coding, duplicate charges, or services you didn't receive. If the insurer denied coverage, use the appeal process in the plan documents and ask the provider whether collection activity can be paused while the dispute is reviewed.

Payday-loan limits vary by state, lender type, and product. Don't rely on a supposed nationwide 36% federal cap without checking the specific law and agreement.

Escalate in the right order

Use an escalation ladder rather than sending the same message everywhere:

1. Business: Send a short written complaint to customer service, billing, compliance, or the executive contact listed in the agreement.
2. Payment provider: Open the fraud or billing dispute before the provider's deadline.
3. Regulator: Report scams to the FTC. Use the CFPB for covered consumer-finance problems and a state regulator or attorney general for businesses under state oversight.
4. Contract process: Check for arbitration, mediation, or a warranty dispute program.
5. Court or legal help: Small claims court may be practical for a modest, documented loss, but filing limits, fees, service rules, and deadlines vary by state and court.

A strong complaint states what happened, what evidence is attached, what remedy you want, and when you need a response. Avoid insults, unsupported legal threats, or a demand for more than the documented loss.

Rules people often misunderstand

• There is no single federal 30-day return right for every U.S. purchase. The seller's policy and applicable state or federal rule control.
• An FTC complaint doesn't guarantee individual recovery. It supports enforcement and reporting; it isn't a private refund process.
• The 60-day credit-card billing-error deadline isn't a universal deadline for every payment dispute. It doesn't automatically apply to debit cards, cryptocurrency, cash, or every chargeback.
• Magnuson-Moss doesn't promise an automatic refund. Start with the written warranty and its remedy.
• A lemon-law remedy isn't triggered by the same number of repairs in every state.
• A merchant refund and a bank dispute are different requests. Contacting one doesn't always start the other.

Before you close the file

• [ ] I identified the payment method and contacted the correct provider.
• [ ] I checked the relevant deadline and kept proof of notice.
• [ ] I saved statements, receipts, contracts, messages, screenshots, and case numbers.
• [ ] I secured accounts and reported exposed identity information.
• [ ] I asked the business for a specific remedy in writing.
• [ ] I reported suspected fraud to the appropriate agency.
• [ ] I recorded every response and follow-up date.
• [ ] I checked whether state law, arbitration, small claims, or legal assistance applies.

Before you send anything, put the provider's response deadline in your calendar and keep the proof of filing in the same folder as your evidence.
