Chess.com Account Disabled Mid-Tournament, Urgently Needs Support

During a game in a tournament on Chess.com, my account got disabled without any reason. I value my account greatly, so I would appreciate your assistance. I've dedicated a lot of time and money to my account and worked hard to achieve these levels. I have a hunch that another individual could be accessing my account. I've reached out to support multiple times but still haven't heard back. I kindly request your understanding and support in my current situation. Your assistance would be greatly appreciated. Please restore access to my account promptly.
