Random Ban?

I'm not sure what just happened. I was just playing a ranked match, won and then instead of going to the Summary Screen it disconnected me. When I tried logging back in I was given a message saying I have been permanently banned from the game. I have no clue why. I haven't been reported, I haven't done anything to my knowledge. I didn't even get a reason. The bad part is it says to check my e-mail and I don't remember which e-mail I used to set up this account. Can someone please tell me if they have had a similar issue?
