Please Reactivate My Whatsapp Account

I am using WhatsApp on a Vivo V29 device and on 14 October my account was suddenly banned. When I tried to log in, I was shown a screen stating “This account can't use WhatsApp” and that I had violated the Terms of Service. I do not know what concrete action allegedly violated the rules and I was not given any clear explanation beyond this generic message. I immediately requested a review through the app on the same day. Afterwards, I received an email from WhatsApp Support stating that my account was banned and that this decision is final. The email included the ticket number 1135389058815918, but again did not explain what exactly I supposedly did wrong, and they refused to reconsider the decision. I respectfully request that my WhatsApp account be reactivated and that my case be re‑evaluated instead of being closed as final without a transparent explanation. I also ask for clear information about what exact behavior is considered a violation in my situation so that I can avoid any issue in the future.
