Most other companies will allow you to obtain a refund despite the registration of a key, Blizzard included. I'm going to assume that if companies like that will issue refunds as long as you have legitimate issues when it comes to playing the game or actually accessing your account they'll warrant out refunds. Still though, even if they don't I'll just end up taking it to the bank and getting a charge back. I'd still rather show my bank that I was willing to communicate with the merchant beforehand instead of going straight to the Charge back. So it's really up to Square to be a good sport. If not, I'll end up getting the refund anyways. I just want to try to do it in a civil fashion first.
