What should you check first?
- Confirm verified account status, matching card name and a supported US state.
- Check issuer approval, available balance and Kraken's displayed card limit.
- If charged without crypto, inspect the order status and contact the issuer about the pending authorization.
When should you stop?
Do not repeatedly retry a pending payment. A preauthorization may appear on the bank statement without a completed trade.
When should you contact support?
Ask the card issuer about a remaining pending charge. For persistent exchange errors, use Kraken support with the order reference.
Use the help centre linked from the exchange's official website. CoinBBank cannot access your account, approve a payment or recover a transfer.
