If a Buy Now, Pay Later (BNPL) payment is wrong, the right first contact depends on the problem. The merchant usually handles delivery, returns, product condition, and refunds. The BNPL company handles its order-dispute process and payment plan. Your bank or card issuer handles a payment dispute or an unauthorized transaction through its own procedures.

Don't assume that every BNPL complaint has the same deadline or pauses every installment. A missing order, an unposted refund, and an unfamiliar payment need different treatment.

Quick answer: what to do about a BNPL complaint

1. Classify the problem. Is it a delivery issue, damaged or incorrect product, return, missing refund, wrong amount, or fraud?
2. Save the records. Keep the order confirmation, plan details, tracking history, return receipt, refund confirmation, statements, and messages.
3. Contact the merchant for a sale-related problem. Say what happened and request a specific remedy.
4. Open the BNPL provider's order dispute, if available. Use the order-specific option in the logged-in account and choose the reason that matches the facts.
5. Contact the bank or card issuer for an unrecognized payment or possible chargeback. The process depends on whether the payment used a credit card, debit card, prepaid card, ACH, or another method.
6. Ask what happens to upcoming installments. A complaint alone may not change the payment schedule.
7. Escalate with a written timeline if necessary. Keep watching any provider or bank deadline while you follow up with the company or consider a complaint to the CFPB or an appropriate state agency.

Match the problem to the right route

For a voluntary return or a change-of-mind request, the merchant's stated return terms are usually the starting point, subject to any applicable law. The BNPL provider's terms determine how it reviews an order complaint and applies a merchant credit to the plan. Neither process automatically replaces the other.

A buyer-protection policy is also a company policy, not necessarily a legal right to a refund. Klarna's U.S. Buyer Protection policy gives examples of specific order problems that may qualify, including receiving only part of an order or receiving damaged goods. The examples also distinguish those problems from disclosed scratches on a used product, a broken screen described in the listing, or a product that simply fails to meet expectations.

Collect the records before you file

Support staff can act on a clear timeline more easily than on a series of disconnected messages. Gather:

• Merchant name, order number, purchase date, and total price
• BNPL plan number and installment schedule
• Product listing, advertised description, and return terms
• Shipping information, tracking history, and delivery photographs
• Photos or video of damage, missing parts, or the wrong item
• Messages with the merchant and BNPL provider
• Return receipt or return-tracking record
• Merchant refund confirmation, including the date and amount
• Bank or card statement showing the payment
• Screenshots of the account balance and future installments

Use the provider's logged-in support channel where possible. Don't send a full card number, password, one-time passcode, or unnecessary identity documents in an email or social-media message.

A short complaint summary can include the facts support will need:

On [date], I placed order [number] with [merchant] for [$amount] using [BNPL provider]. The problem is [specific issue]. I contacted the merchant on [dates] and received [response or no response]. I am requesting [refund, correction, replacement, or fraud review]. Please confirm the case number and explain what happens to the remaining installments.

Step-by-step dispute process

1. Ask the merchant to fix the underlying order problem

For a late shipment, missing item, damaged product, return, or cancellation, contact the merchant first. Describe the problem accurately and state the remedy you want, such as delivery, replacement, or refund. Ask the merchant to confirm any promised refund in writing.

If the payment is unauthorized, don't wait for the merchant to respond. Use the fraud steps below and contact the BNPL company and funding institution promptly.

A slow response from a merchant isn't the same as fraud. Calling a delivery or product complaint "fraud" can put it in the wrong review category and delay the dispute.

2. Open the provider's order dispute

If the merchant doesn't resolve the issue, use the order-specific help or dispute option in the BNPL account. Include the order number, dates, amount, and documents. Explain whether the product was not received, was incomplete, was damaged, or materially differed from its description.

Some providers ask the shopper to contact the merchant first. Others set their own filing windows and instructions. Read the deadline shown in your account and the provider's current terms rather than waiting indefinitely for a merchant reply.

3. Find out whether installments are still due

Filing a complaint doesn't necessarily cancel or pause the schedule. Ask the provider, preferably in writing:

• Is the next installment still due?
• Has the disputed amount been put on hold?
• What happens if the merchant issues a partial refund?
• How will a missed payment be treated while the review is open?
• When will the revised balance and due dates appear?

Save the answer with the case number. If the provider hasn't confirmed a pause, don't assume that all future installments have disappeared. Continue checking the account and ask how to handle any amount outside the disputed portion.

4. Answer requests in the dispute portal

Upload documents through the channel the provider identifies. Put the order number in each message and answer each question directly. A simple timeline is often more useful than a long explanation:

• Purchase date
• Promised delivery date
• Date you noticed the problem
• Dates you contacted the merchant
• Merchant response
• Return or refund date
• Amount still shown as due

5. Check that the result reached the BNPL plan

A merchant's message saying that a refund was issued and the BNPL account's balance are separate records. After the merchant processes the refund, check that:

• The refund amount is correct
• The plan shows the credit
• Future installments were recalculated or canceled as appropriate
• Any fee or other amount connected to the disputed transaction is explained
• The order no longer appears unresolved

For a partial refund, ask how the provider calculated the remaining balance and installment dates.

Provider-specific points

Klarna

Klarna's U.S. Buyer Protection policy describes particular order problems rather than every form of dissatisfaction. Its examples include buying four glasses and receiving two broken ones, or ordering three items and receiving only two.

The same policy gives examples that may not fit those covered problems: scratches disclosed on a used table, a broken phone screen highlighted in the store's description, or TV picture quality that is lower than expected. Save the listing, photos, tracking information, and merchant correspondence before using the order-help route in your Klarna account. Check the current policy and account instructions before filing.

Sezzle

Sezzle's dispute instructions say disputes must be filed within 90 days of the purchase date. The instructions direct shoppers to open the order in a web browser, select Get help with this order, and complete the form. That feature isn't supported in the app according to the page.

The same page says Sezzle's disputes team evaluates the submission over the next two to three business days and provides next steps. The 90-day window is Sezzle's published policy, not a deadline for every BNPL provider.

Sezzle's separate chargeback guidance describes a chargeback as a request to a bank to reverse a card payment. It says the process can take a couple of months depending on the bank. You can check for active chargebacks in the Sezzle Dashboard under Orders. The page also says that paying installments associated with an active chargeback will close that chargeback, so follow the instructions from both Sezzle and the bank rather than guessing about the next payment.

Afterpay and Affirm

For Afterpay or Affirm, use the specific order screen and current terms for that provider. Save the deadline and payment instructions shown in the account. A Klarna or Sezzle process shouldn't be treated as the rule for another provider.

A BNPL dispute is not the same as a chargeback

A provider dispute asks the BNPL company to review an order or account problem. A chargeback asks a bank or card issuer to reverse a payment through the applicable payment-network process.

Sezzle's explanation of a chargeback concerns a card payment. Before asking a bank to reverse a payment, identify how the BNPL transaction was funded. Credit card, debit card, prepaid card, ACH, and other payment methods may have different procedures and deadlines.

Tell the issuer about any open BNPL dispute, merchant refund, or credit already received. A chargeback isn't a guarantee that the payment will be reversed, and a duplicate recovery can create a new balance problem.

What to do about suspected BNPL fraud

Contact the BNPL company and the bank or card issuer as soon as you see an unfamiliar plan or payment. Ask the provider to secure the account, investigate the transaction, and explain whether another installment is scheduled.

Also:

• Change the account password and turn on available security features
• Check the email address, phone number, shipping address, and saved payment methods for changes
• Save the alert, statement, transaction date, and amount
• Ask for a fraud case number
• Don't share verification codes with someone who contacts you unexpectedly
• Tell each company exactly which transactions you recognize and which you don't

An order that arrived late is a merchant-performance problem, not automatically an unauthorized transaction. Report the facts that support the category you select.

If the company doesn't resolve the complaint

Follow up in writing after the provider's stated review period or after it misses a promised response. Include the case number, a short timeline, the amount involved, the documents you already sent, and the remedy you want.

The Consumer Financial Protection Bureau information page on USA.gov says the CFPB accepts consumer complaints and supervises certain financial companies, including banks, lenders, and large non-bank entities. You can submit a complaint through the CFPB complaint portal. Whether the CFPB handles a particular BNPL company or product depends on its jurisdiction.

A CFPB complaint is an escalation channel, not an automatic refund and not a substitute for a provider or bank deadline. If a card issuer has given you a dispute window, don't let that window expire while you wait for an agency response. For a state-specific concern, use the official consumer-protection or financial-regulator website for that state.

Mistakes that can weaken a complaint

• Waiting for the merchant until the provider's filing window expires
• Treating a refund promise as proof that the BNPL balance has been corrected
• Filing a chargeback without telling the issuer about an existing provider dispute
• Describing a delivery or product-quality issue as fraud
• Stopping every installment without asking how the open case affects the schedule
• Sending sensitive account information through an unverified channel
• Relying on phone calls without recording dates, names, and case numbers
• Applying one provider's policy to another provider

Frequently asked questions

Does opening a BNPL dispute stop my installments?

Not automatically. Ask whether the disputed amount is paused, whether the next payment remains due, and how a missed payment will be treated while the review is open. Keep monitoring the account until the provider confirms the change.

How long do I have to file a BNPL complaint?

There is no single deadline to use for every provider and payment method. Sezzle's published dispute instructions state a 90-day period from the purchase date. Other provider and bank deadlines can differ, so check the current terms and account instructions as soon as the problem appears.

Can the BNPL company make a merchant issue a refund?

Not necessarily. The merchant's return and refund terms usually govern the sale, subject to applicable law. A BNPL provider may review the order under its own buyer-protection or dispute policy, but that policy doesn't automatically replace the merchant's terms.

Is a chargeback guaranteed to reverse the payment?

No. The bank or card issuer reviews the request under the process that applies to the payment method. Submit accurate records and disclose any merchant refund or BNPL credit already issued.

What if the merchant issued a refund but the BNPL plan still shows a balance?

Ask the merchant for the refund date, amount, destination, and reference number. Send those details to the BNPL provider and request a written explanation of the remaining balance and future installment dates. Keep the provider's case number and the merchant's confirmation.

When should I contact the CFPB?

Give the company a reasonable opportunity to address the issue, or contact the CFPB sooner if doing so helps you preserve another deadline. Include a factual timeline and supporting documents. The complaint doesn't replace a provider or bank dispute, so keep using whichever route has the earliest deadline and save the CFPB confirmation number.
