LOL The pharmacist is one of the member who are always in front of my eyes. I don't reply always but looking at his understanding about tech savvy I do not think he will take the time to create a telegram channel then will text you there. It was defiantly someone else and you are mixing him with The pharmacist.

Now about the negative trust, if you talk to him with respect then I am sure he will understand your points. But the way you are approaching it's not gonna help.
