When you're trying to arrange your match and one of the following situations happen:
1) There's no reply from your opponent to your PMs.
2) The arranged time to play your match arrives and he doesn't show up.
You CAN NOT report false scores, like 6-0 6-0 for example.
The match is not played, and the only thing you can do is contact the host to let him know about it and wait until the deadline to see what decision makes the host after after evaluating the PMs sent between the two opponents.
Reporting false scores is a serious infraction.
