Acc hacked + banned

Hey,

When i tried to login into my account, it said im being banned.
I weren't playing for a very long time.

The Account name: sahmas

Alright, as i said it is banned and it got hacked. Somone sold probably all my chars, which was around 1k Euros. Everything was donated. I had Shadowmourne, i had fullgeared season 8 characters, i had everything. I just have a few Emails in my Mails where i can see, someone wanted to change all my infos and he was going to sell my chars. What after that happened, i have no idea. He probably got the E-Mail SOMEHOW changed, even if he wasn't even the owner.
Just as a notice: That happened in jan/feb 2021. From that date are the E-Mails

At first, it would be very nice, if you just unban my acc and change back to my datas because it is my Account and not this *******. I want to check how big this guy has damaged my account..

I would be very grateful if you can help me get my stuff and my acc back.

Thanks
