Account's hacked?

Hey I dont how else to word this, but my toon's are gone, I havent logged in in a long time, I just happen to try it and everything is gone, my 2 step authenticater is turned on or was. What do I need to do? So much money was spent and I hate to see if just gone. Is there anything that can be done? I still have all the history on this account to prove. I can provide any proof of this being my account. Please help

Log in and check in game. Most likely flagged for a rename due to inactivity and you won't see them on wenbssite/ armory until you log in game and set a new name.

Thank you! Your a savior for something so simple!
