Hello,
did you run through this procedure?
http://helpx.adobe.com/x-productkb/policy-pricing/account-password-sign-faq.html >>> I want to change my password, email, or account information. >>> Change your account information >>> Chat
... and the chat hadn't been ok? Sorry but if necessary, please try it again (if "open"), I had the best experiences.
On the other hand, here sometimes Adobe staff members are writing. You could try to write to ne of them per email.
