Hi, I used to live in the UK, and recently moved to Mexico. I tried to buy a Xbox Live Golden Membership, but it would not let me buy it with my new Mexican credit card because the Billing Address Info does not recognize my new Zip Code as a valid one. I guess it is because it is not a UK Zip Code. I tried editing my location from UK to Mexico but still would not let me buy it. What can I do to solve this issue?.
