Hello, I would like to ask for your help, unfortunately at the end of last year a hacker stole my steam account and along with that stole my entire inventory and worse, he used cheats on dayz and was banned. The person who stole my account would certainly be Chinese because they changed the account store to Chinese. I would like to ask them to remove the ban because I was not at fault in this, it is bad enough that I was left without my inventory, I still lost the game. If you can confirm you will see that at the time of the ban the IP was not from Portugal as it always was and that is because I am Portuguese. Please help me
