That's a first.. never had issues with PlayAsia whether I use Credit Card or PayPal.
GameStop US was a hassle for me though. I had to fax over my details, and it was only strictly fax. No scanned copies via e-mail.
Problem was when I went to the PostOffice to help me get it faxed over before or after work, it didn't go through. I suspected it was because they switched off the fax machine during non-working hours but they claim they don't. In the end, I managed to get an online site to fax it over.. What a hassle..
