WhatsApp Blocked My Account From Logging In

I have been using WhatsApp on my mobile number 9356929*** and my account has been directly banned. When I try to log in, the screen shows “This account can’t use WhatsApp” and only gives the option to register a new number. I do not know the reason for this ban and I cannot access my WhatsApp at all. I have already contacted WhatsApp support about this situation, but my account is still not opened. I request that my WhatsApp account be checked again and that the ban on my number be removed so that I can use my WhatsApp normally again
