Paid for Telegram Premium but Can’t Access Premium Features

I purchased a Telegram Premium subscription on my Android phone and paid for it by charging the payment to my mobile phone bill. However, since approximately September 6, 2026, whenever I try to use my Premium account, I receive an error message saying, “This item is already yours,” and I cannot log in to my account. The app behaves as though I have an active Premium subscription, but I cannot access any Premium features or log in properly.

I am requesting that the Telegram Premium service I paid for be properly and fully activated on my account, that the error be resolved so I can log in to the app normally, and that I be able to use the Premium features. I ask that this issue be investigated and resolved as soon as possible.
