Just sell the coins and go on. I don't keep in my wallet those coins whose teams show aggression and hand out the ban to investors. In my opinion, the investor has the right to ask everything he wants, of course in a polite manner and without insults. And many projects' managers spend a lot of time to clarify the situation, etc. Teams that are afraid of criticism are the bad choice of investments. Criticism is the stimulation of growth. Just finish it and move on.
