DNF Loss after opponent disconnects

I was winning a game 4-1 in UT Champs, pressed start to do subs around the 70' minute after scoring a goal. I went on the replays to check something quickly and while being in the replay my opponent quit, and suddenly the game crashed. When I logged back on, the game prompted me with a DNF warning and got the loss in Champs even if my opponent is the one that disconnected. 

I am furious!!! MY OPPONENT QUIT WHILE I WAS WINNING AND I GOT A DNF LOSS
Robbed of a win and better rewards, this was my second to last game, I would have ended with 9W... Missed out on a guaranteed promo card.
