Facebook Closed My Advertising Account Without Warning and Ignored My Messages

I have been using Facebook for a long time as a corporate identity and have also paid for ads. However, Facebook suddenly closed my advertising account without providing any warning. This action has caused significant inconvenience, and I am deeply dissatisfied that my account has not been reopened despite my efforts. I have sent multiple messages to address the issue, but I have not received any response. I am filing this complaint to express my dissatisfaction.
