Account Hacked Even With Authenticator

Yesterday my main account was hacked around 8:30pm EST. So I created this account in order to post in the forums. My phone number linked to said account is apparently no longer tied to the account - nor are my friends able to see my gamertag. Does anyone know what to do? I’ve submitted ticket(s) but have seen no other way to contact support. Does Blizzard support have a direct email?
