My Steam Account Was Stolen

My Steam account got taken, and I’ve been working on getting it back for the last four days. I quickly reached out to Steam Support and provided the receipts for the games I had bought earlier as evidence of ownership. Unfortunately, I have not received any useful or comforting reply. I had hoped for some sort of update or acknowledgment regarding my case by now, yet all I’ve received is complete silence. I’ve invested considerable time and resources into this account, and witnessing it in another person's control without any solid support from Steam has truly undermined my trust in the platform. I just want to get back into my account and enjoy the gaming experience I've developed over the years. My account name is 80bedirhan80. I genuinely hope this gets addressed promptly.
