Hello house, I am applying to the University of Houston and when I input my card details to make payment, I keep getting this message:

There was a problem processing your payment: The reason given was: [/b][ADDRESS VERIFICATION MISMATCH. The Billing Address did not match that of the cardholder. Please correct. ][b]

Please verify your payment information or use an alternate form of payment."

I have tried various mastercards and verified the addresses. I even got someone in the US to try. Still the same problem.

Who could help me out here? Thanks a lot! very important
