Unfair Ban by Valve: Account Problem In Counter-Strike 2

Counter-Strike 2 game banned me for no reason. Yes, for no reason. I have not played the game While I was preparing for the university exams. I received the information that I was banned. It has been months and I still cannot get any answers. My Account was Stolen and I got it back with the help of Steam support team. Did something happen when my account was stolen? No explanation is given to me. It says "I was banned from Counter-Strike 2" as a felony on my account, but I didn't even play the game that month. I want my rights. You have dishonored me and my account. What you wanted from me while studying my exams? There are so many people cheating and why me while not playing the game?
