I have been hacked?

Hello,

I used to play on Warmane back in 2017 and i had lvl 80 ICC Normal geared Priest and Mage, and now when i logged back a week ago i had no characters on my account, when i saw history i saw that someone logged my account recently and i assume deleted my characters? Is there any way i can get them back? Screenshots posted below./

If someone did indeed get into your account you won't get the characters back. Your account is your responsibility, and that implies its safety aswell. Warmane even introduced 2FA so you can't lose your account so easily.
