It seems like responded to something you said to him in DMs going back to the first message in this thread.
Granted, my point is you gotta have more grace going about your business in this game in general. Insulting people and taking it seriously does not help anyone, and you may be burning bridges with people who are trying to help you improve at the game with how you conduct yourself.
I'm not excusing his conduct either, just maybe focus on changing your own behavior if you want people to either help you or negotiate trades with you.
