Where do submit appeals
I was playing chess with a random player and I was doing well. I then realised that because I obliterated him with a good move he quited the game without resigning. I opened a new google tab to do my homework because I was bored waiting and when I came back it said game abandoned when it was his time to play.

If you leave the tab it is possible that the server didn't see a connection and counted the game as abandoned.
