WhatsApp Banned My Account Without Warning or Explanation

My WhatsApp account linked to the number +91 78144 866** has suddenly been banned. I first found out about the ban on 14 September 2026 when I opened the app and saw the suspension message on the screen. I have never violated WhatsApp rules knowingly, and this number is very important for me because I use it to receive messages and calls from my family and friends. The sudden ban has affected my daily communication and caused me serious difficulty in staying in touch with them. I kindly request that you urgently review my account and unban the number +91 78144 866**, or at least clearly explain the exact reason for this ban so that I can avoid any such issue in the future.
