Need "forgot account email" function

I have two accounts, both of which I remember the account info for, but one is locked and I can't remember the email I used to set it up with. How the hell do I find that out? Every recovery option sends the 'code' to the accounts email. I've checked all the email accounts I usually use, and nothing from Warmane in any of them. I haven't played in about 7 months so I'm not surprised I can't remember my log in info after Warmane merged and everything changed.

How can I recover my account without the email? ;/
