If you received an AVS mismatch, it means that the address provided did not match the billing address of the cardholder. If you had an error with your billing address, we did NOT charge your card.

An ERROR stops the transaction. Even when the transaction failed, the bank has already received the funds request. As a result, the bank or the getaway holds the money for a few business days for security reasons (exactly how long, it depends on the bank).

It will return to your account. It generally takes 2-3 business days. You may contact your bank to find out how long is the hold for.
