Problems when paying by bank card

Sometimes when paying with Visa / MasterCard credit cards, difficulties may arise. The most common ones are:

1. The card has a limit on the payment of purchases on the Internet
2. The plastic card is not intended for making payments on the Internet.
3. Plastic card is not activated for making payments on the Internet.
4. Insufficient funds on a plastic card.

In order to solve these problems, you must call or write to the technical support of the bank in which you are serviced. Bank specialists will help them to solve and make payment.
