Blizzard Account - contact support not working

I have been trying to change the account (the same account I am posting on by the way) email address but somehow the system will not let me change because “this email is already in use”.

This is my only battle.net account I have and I am certainly not aware of a second battle.net account at the new address ever being used…

I just double confirmed by searching for “battle.net” on targeted gmail. My best guess? It looked at the linked gmail (via conneciton) and treated it as “in used”. So I removed that. No such luck and it still throw out the same error “in used”.

I tried to create a new support and THAT was painful and after going through the whole process to get to a “website ticket support” form and it will NOT let me click submit ticket. It is just greyed out no matter what I do and in different browsers.
