If i buy something expensive they call to cardholder?

The bank wont call the cardholder for 400 bucks, atleast the chances of that are very low. The shop could call the number provided upon the purchase tho so make sure you provide a number that u have access to. In terms of VBV the shop usually has an image that reflects the vbv security, once you will have more experience you will understand what im talking about
