diddl
it is almost identical to what I did to myself by accident a few years ago.
I had one account I started with, but when I got my phone and was setting up app, I added a different account by accident! so for a very short time I had 2 accounts! 
Of course I told MNHQ about it all, who "blocked" the 2nd email, but that was my phone so I received no emails from that point onwards because I couldn't access 1st account from phone!
so if I ever reported a post (good or bad) in the last 2 years I simply didn't know what HQ replied to it. For all I know if I had been to be banned I never would've know unless they'd thought to PM me!
so, DH found the old account. requested new password for me. opened password reset email. reset password
I used this to log on . it worked
but then I got an email "enter password to confirm email address change" and that didn't work. kept on getting "error occured"
so looked at my acvount. it still had my 1st email address

contected MNHQ, who has literally just has sorted it (I won't disclose how, for safety) but the fiddling they did worked, got another "confirm new email address" message, I entered new password - it's all good now, account shows my new email. HURRAH!
Apologies for essay, just wanted to say that they can sort your email change if needed.
does this help you?
