Why can't I complete the payment with my credit card?

Statistically, most of the unsuccessful payment attempts are due to the systems of additional verification introduced by the circuits of credit, such as 3DSecure and Verified by Visa.
Other impediments to the payment can be related to the limits and permissions of the card for which we invite you to contact your bank. In any case, as long as our system does not report the payments accounted, it is possible to make all attempts of payment you want.
We know only the outcome of the transaction and, if it is positive, we will confirm instantly the order by email.
In any case, our customer service is always at your disposal.
