Well I have encounter opponent like that.  BTW it is not appropriate to put the other users name.  You could be banned for that, i think.  You should have just disable the chat & piss him off by making him wait for every move.  This type of people deserve that.  However I do agree with that person, winning 1 match does not qualify you to be better than that person but the fact is he lost & you won.   

Is the crybaby Asian?   The one in the picture looks Asian and the grammar is a little off.  Very cute picture, by the way.

I didn't understand the complaints.  Or anything your opponent was saying, really.  time issue?  clicking issue?  cheating issue?  I couldn't figure it out.

That person is over 2+++ turn based rating who could not take losing to 14++ turn based rated player.  Even in 960 chess where their rating were about the same.
