Is it just the one guy in the square Enix deal page? My account is fine.
My account is also fine. I wouldn't care if they closed it anyway - I'd just go make another. No biggie...
In fairness I rarely use Amazon, I find their service to be poor for preorders unless you fork out for delivery. The only time I use them now is for odd bits and bobs like earphones and gifts.
EDIT - (In the UK)
