Klarna

In short

Contact the store first, then use Report a problem on the purchase in the Klarna app; Klarna pauses the payment while it looks into it, and claims must be raised within 120 days. A return does not reduce what you owe until the store's credit reaches Klarna, so report the return with tracking to pause the payment. Pay in 4 payments are taken automatically and a late fee of up to $7 can apply after 10 days. In the 12 months to June 2026, 6.9% of CFPB complaints about Klarna closed with relief, and 9.3% got a late response. Klarna says that if a message is not in your Klarna Inbox, it did not come from Klarna.

Traps and fine print

• A return does not change what you owe under Pay in 4 until Klarna receives a credit from the merchant, and merchant credits do not count as payments. Klarna Pay in 4 agreement
• Pay in 4 installments are charged automatically every 2 weeks. A failed payment can be retried up to two more times and charged to your backup payment method after one day's notice; change the payment method at least three business days before the next payment. Klarna Pay in 4 agreement
• A late fee of up to $7 may be charged if a payment stays unpaid 10 days after its due date, capped at 25% of the purchase amount, and late or missed payments may appear on your credit report. Klarna Pay in 4 agreement
• Buyer protection claims must be raised within 120 days, and Klarna decides at its reasonable discretion whether to refund or remove the payment obligation. Klarna: buyer protection
• On May 12, 2025 the CFPB withdrew its 2024 interpretive rule that treated BNPL lenders with digital accounts as credit card issuers under Regulation Z. Do not cite it as a source of dispute or refund rights. CFPB: Buy Now, Pay Later products
