Online tournaments

So I signed up for a tournament made it to the final round and the I joined and waited for the kid to join and finally he joins and then we got into the match and then he left so I was like let’s goooooo I just won but no it didn’t count so me and him join the queue again and we get in and then he leaves again so this happened about five times and since he left he glitched the game so it counted as a win for him and all he did was leave 5 times
