Telegram Won't Let Me Log In With My Phone Number

My Telegram account linked to the phone number +2519529459*** has just been banned. When I try to log in, the screen shows “Sorry. This phone number is banned.” I do not know the reason for this ban and I would like my account and number to be recovered. I have already tried to contact Telegram support but my problem has not been resolved. I kindly request that you review this ban on my number +2519529459**, explain clearly why it was imposed if you believe there is a violation, and reactivate my account if possible.
