WhatsApp Got Banned For No Reason

I have been using WhatsApp on my Samsung Galaxy S7 for personal and business communication, and on January 30, I suddenly received a message stating that this number can no longer use WhatsApp. I have not violated any rules to my knowledge and have not done anything inappropriate with my WhatsApp account. The affected number is +23491218731**  I urgently need this number to be reactivated because I use it both for my business and to keep in touch with my friends. I tried basic steps on my phone, but the same message continues to appear, and I still cannot access my WhatsApp account. I kindly request that my account and number be reviewed in detail and that my WhatsApp access be restored as soon as possible, or that I be clearly informed about the reason for this restriction if there has been a mistake.
