Here are a few reasons why a credit card may fail:
- "General decline of the card. No other information provided by the issuing bank. Request a different card or other form of payment.”
- "Insufficient funds in the account. Request a different card or other form of payment.”
- "Invalid account number. Request a different card or other form of payment."
Remember, you can always add or update your credit card details in your AdBuilder account by updating your ‘wallet’.
