Can't buy stuff

When I try to buy something it says "This payment cannot be completed and your account has not been charged. Please contact your merchant for more information" and I have no idea what to do

Contact your card issuer or bank and see if there is a problem.

Have you accidentally cancelled your online direct debit mandate?
