I dont wanna be that one guy who laughs at OP and goes "thats what you get for playing a blizzard game" but...
You're stupid.. you are being that one guy
if you explain the situation instead of being a screaming autist like you usually are, beachbum, then they would be much more helpful
I was in the same situation and I just provided a screenshot of me ingame and they took it, they're people with brains.. it's common sense that if you can provide any kind of proof that it's you then they can fix the problem easily
