Unable to Use Telegram After Sudden Account Ban

My Telegram account linked to the phone number +91 7859094*** was banned about two months ago without any explanation. I was using the account in a normal way and did not do anything unusual or use any third‑party or modified Telegram applications. After the ban I tried to reach Telegram support, but I have not received any reply or message so far. I still do not know the reason for the ban and I am unable to use my number with Telegram. I request that my Telegram account be unbanned as soon as possible so that I can use the service again.
