Card transactions can be declined for many reasons. Please make sure that all the card details you have entered are correct and that there are available funds on your bank account.

Furthermore, some issuing banks may block online transactions of unusual frequency or they can block international transactions for security reasons. Please contact your bank in order to get clarification on their card payment policy.

If the problem continues we suggest that you either use a different card, or one of our alternative billing providers, or payment methods.
