In May 2016, two channel URLs were "stolen" in Telegram, is it possible to somehow see the history of URL renaming in telegrams?

Question

Burglary protection

In May 2016 there was a vulnerability in telegrams https://habrahabr.ru/company/pt/blog/283052/ due to which my account suffered. Two channel URLs were "stolen", stupidly someone logged in from my account and renamed the url to "clumsy", thereby freeing them for their own use, is it possible to somehow see the URL renaming history in telegrams? To poke tech support with their nose there, which was a direct hacking of the account.
And before this incident, I didn’t go to telegrams for a month, the Internet on the phone is always turned off.
On the telegram servers, these URL renaming actions should be listed in the history, there should be other people's ip from other countries, all 2 two urls were transferred to some Arabs.
Technical support from May 2016 to February 2018 generally ignored me, I wrote to them through the website and via telegram. This week, technical support answered, but they did not give a clear answer, nothing is moving, they are avoiding questions.
How to be?
