Telegram Account Banned Without Reason

I am writing to complain about the unjustified ban of my Telegram account linked to the phone number 8978902***. When I recently reinstalled the Telegram application and tried to log in, I discovered that my number had been banned without any prior warning or clear reason. This account was not used for spam, bulk messaging, promotions, or any suspicious activity. I was simply trying to install and use Telegram, and I was surprised to see that my number is already banned. I contacted Telegram support by email about this issue, but I have not received any response so far, which makes the situation even more frustrating. I kindly request that my number be unbanned and my Telegram access restored as soon as possible, or at least that I be given a clear explanation for the ban if there is any specific reason. I expect this issue to be reviewed urgently and resolved so that I can use Telegram normally again.
