WhatsApp Account Banned Despite Following All Terms of Service

I have been using my WhatsApp account with the number +9665943465** for about five years without any problems. Today at around 5:30 I suddenly lost access to my account and started receiving a message saying that this account cannot use WhatsApp, with an explanation that the recent account activity does not follow WhatsApp’s Terms of Service. No additional reason or error code is displayed. I do not use any unofficial or modified WhatsApp applications, and I have not engaged in any unusual activity such as sending bulk messages, spamming unknown numbers or similar actions. This is my main number that I use daily to communicate with family, friends and important personal contacts, so this unexpected restriction is causing me serious difficulties. I kindly request that my account be reviewed in detail and that this decision be reconsidered, as I believe the restriction is a mistake. I am ready to provide any additional information or documentation if needed. I ask for my WhatsApp account linked to the number +9665943465** to be restored as soon as possible so that I can continue using the service.
