Then why participate in the tournament if family/work prevents you from completing the matches within the 2-week timeframe? Sorry if I'm being blunt, but such excuses are an attempt to have your cake and eat it too. The tournament rules are the same for everyone. Don't the others also make sacrifices to play their matches on time?
Unexpected situations do happen... there are many possibilities... but that doesn't mean you should act like an animal, right?
