I believe my account got hacked

Hello, I really do not know what to do. I was playing COD all day yesterday and I tried logging in this morning and it said that their is no battle.net account in use with the email. I thought it was an error and kept trying. I ended up creating a new account under the same email. I tried playing COD again and it said I do not own the rights to the game. My tag before was Malibu#1754. I received an email on the second (I just noticed now) saying my email address has been updated. This is why I believe it was hacked. I have NEVER shared my account with anyone. What do I do? I submitted a ticket, but I don’t want to prolong it and lose out on the hundreds I’ve spent on my account.

Thank you everyone for helping - this is a horrible feeling.
