I was hoping this joke of support would get their crap together and do some proper fixing of the issues that their stupid, convoluted system caused without resorting to re-ordering the game. At least I know to expect sub-par service from them in the future.

Before I go, I got another response from their support about the issue. It was the same response as the one I got yesterday.

Thank you for contacting the Square Enix Support Center

We apologize for any inconvenience in this matter. The issue regarding the region of registration codes has been resolved. Please retry your code again at the beta registration code page for your proper region.

Proof positive that they don't even read the detailed information that you include when submitting a support ticket.

I let them have it in the support survey they sent me. That'll show 'em.
