Account Email Changed and can't log in

Hey guys,

My battlenet was Rafid25#1366 and my account was associated with my gmail account. Today morning I was notified that my account email was changed all of a sudden without my request. I tried logging in with my gmail and it said “account not found” and I had to make a brand new account which I am posting from right now. I have filed a ticket to blizzard but this is so strange this happened all of a sudden. I was wondering if one of the moderators or if anyone else can shed light on what else I can be doing at this time. I had multiple years of progress on multiple games and this is a disaster. Please help someone =(
