My dev account is blocked

For un unknown reason, my Apple ID has been blocked. Since I can not connect anymore to my developer account !

I've asked to unblock it (iforgot.apple.com) but according to support the unblock sequence is not send because this Apple ID is in used.

I need help to unblock my ID in order to manage my app....

note : I use an another account to post this messages.
