I confirmed a screenshot with minerjones on telegram whose username was initially mtmantis and later changed to minerjones on telegram. However, now my 26BTC are gone and also their accounts on telegram are deleted.
I feel sad for your loss even though you did not provide any evidence, 26BTC is a really huge amount that I can collect in about 10-20 years, Telegram is not a good platform for you to do any transactions through, as anyone can message you and impersonate the username of another person, and he can delete private messages between you and him in seconds, and you will not be able to recover them. I do not know @minerjones, but what I see is that he is a member who enjoys a lot of positive trust in his account. It is certain that the scammer who stole your money imitated his username on Telegram and contacted you. It would have been better for you to carry out your dealings through the forum away from Telegram or any of the other platforms, as the forum has private messages that you can communicate with whomever you want through.
