There was a problem processing your credit card.
The transaction has been declined because of an AVS mismatch. The address provided does not match billing address of cardholder."
The informations are correk and I tried with two cards... I always get the error message... I sent an e-mail to 'firstname.lastname@example.org
' two days ago but no answer yet... What can be done ?
