I have inserted and confirmed my information, but an error is reported when I get to the bank gateway, what I can do?
We are taking orders as normal. Be sure to use VISA, Mastercard and 4B, correctly filling in all the data and reviewing the firewall and antivirus software with your network administrator if ne cessary at a later time to avoid conflict with other users.
When I try to pay with the credit card it asks me to insert the 'Codvalido' and I do not know information should I fill. Could you help me?:
As stated on the website of the bank, the validation code is a Three part number code on the back of Visa or Mastercard (for Master cards does not exist. Instead enter the last three digits of the card). This number appears in italics at the top of the signature panel. On some cards the card number printed in italics on the signature panel contains 16 digits (can be only 4), but will always be followed by the validation code, which is formed by the last three digits on the right. On American Express cards the code consists of 4 digits on the front of the card.
I have tried to pay by credit card and payment was denied, however I received an order confirmation eMail. Why is this?
It is simply because, although it has declined the payment, our server continues to issue the order. We do not eliminate the order automatically until is confirmed by the user who made the purchase.
