After fighting with billing services and attempting to find a solution on this forum through numerous other threads created with the same problem i found the solution.
If you get error 202 after putting your credit card info while attempting to upgrade to WotLK... do this:
Enter the last four digits of your credit card in as your area code
Thanks to lack of billing support and technical errors i had to figure this out myself and feel the need to share my findings with anyone else in an equally frustrated state. Hope i helped someone.
