WhatsApp Business Account Banned Without Clear Reason or Explanation

I have been using WhatsApp on my iPhone 12 mainly for business communication, and about a week ago my account was suddenly banned. On the screen I see the message “This account can’t use WhatsApp” and that my account allegedly violated the Terms of Service. I use the number only for normal business messages and I have not intentionally done anything that I know to be against WhatsApp rules. This situation has seriously disrupted my business communication and caused loss of time and trust with my customers, as I can no longer respond to them through the number they are used to. I have not received any clear information about what concrete rule I supposedly violated, so I do not have the chance to correct or avoid the same situation in the future. I kindly request that my WhatsApp account be reviewed in detail and reactivated as soon as possible, and that I be informed clearly about the exact reason for the ban. If there has been a misunderstanding or automatic error, I ask you to lift this restriction urgently so that I can continue using WhatsApp for my business communication.
