I think it's time to quit

Sometimes you have to know when to quit. You can look the other way with some signs but to completely ignore them is stupidity. We had a crazy loss on week one where one team which was 1/16 let us down. It happens. Today was the icing on the cake. 5/6 results had come in. So we are awaiting a 1/9 to fill it up. This dude is 2 sets to 1 up serving for the match. He is 40-0 up on his own serve. Odds on him to win are 1/1000 Cash out is 99% of total. So it's a done deal right? He somehow loses that game loses the next and loses the deciding set on a tie break. So it could be just a bad run. However these are the bets from earlier.

So I can win 10/1 when I bet but as a group bet we lose on a 1/1000 Do I need to say anymore?
