I had this problem for the longest time.
Turns out when it asks for your credit card # and your name, I was using the name of my credit card (MasterCard) when I should have put my actual name (on the credit card) in that field.
That was my problem anyways. As long as it matches up to the information on the XBox dashboard, you should be fine.
