i don't know where i can go to discuss this problem with SE.
my payment method become obsolete.
i register a new payment method but didn't get an email (strange) and my account is still cancelled.
i tried to reactivate it, SE ask for my payment credentials, didn't get an email (strange) and i'm still cancelled.
logout/login didn't do the trick.
of course, my payment method works and i'm on https://secure.square-enix.com, no phishing
