account locked

Yesterday, while I was playing games normally, I was suddenly prompted that my account had been locked. I don't know why, and you didn't give me a prompt or send me an email to tell me the reason.
      I spent $100 and played for at least 8 hours a day, investing a lot of time and emotion into the game. I really like POE2, but now it suddenly doesn't allow me to play anymore. I've sent you several emails, but haven't received any response. I'm very disappointed.
      I didn't do anything against the rules, and I don't know why. If I have any violations, please reply and let me know, and I will make changes.Please unlock my account. My account is: s13608069043@outlook.com
