So, I got the code but it seems I got a PC code and not the XBOX one code, or am I missing something?
It should have asked you at sign-up which code you wanted. Unfortunately, I don't think they have any way of correcting it if the wrong selection was made other than signing up with a new e-mail and waiting again.
That said, if you don't want that PC code, I'll take it off your hands >_>
