This is nonsense. I'll delete both games. If game 31299 was actually won by Xubo and he only posted a wrong replay, then he owes you a rematch of the second game. If it was only one game, then it's really bad sportmanship to report it. It's clear that he really had to go somewhere since it was at the start of the game and not because he'd try to avoid a loss or something.
Replay attached.
