Hello,
Thank you for the report.
I shouldn't have called you a "retard" and my apologies for doing so.
Nevertheless, there were a lot of participants in the event and we were on an extremely tight schedule to ensure that the event wouldn't take too long. You were still in the voice chat and heard other people talking despite being muted, and multiple people told you repeatedly that you need to play one more round in order to close the match off. Because you didn't respond (as it was first to win 3 rounds), we decided that your opponent would win instead of you.
Please read the instructions carefully for the next event and make sure that everything is fine before you go AFKing and blatantly refuse to continue playing.
Thanks.
