Telegram Banned My Phone Number Without Explanation

My Telegram account linked to the phone number +91 81320676** has been banned without any clear reason, and I am unable to use the application. When I try to log in, I see the message “Sorry, this phone number is banned.” I was only using this Telegram account for personal chats and regular communication. I have not been informed of any specific violation and I do not know why my number was banned. Each time I try to access my account, I receive the same ban notification and cannot proceed further. I kindly request that my phone number be unbanned and my access to Telegram be restored, or that I am at least provided with a clear explanation of the reason for this ban.
