Disconnect after opponent quit

I was playing rivals and after I scored my 4th goal my opponent quit. As you will see in the video it fails to put me back into ultimate team. I lost my winning streak I was on, it counted as a loss , I lost some of my dnf rating, I didn't complete my evo stage because of it, I could have lost a rival bounty but I didn't get a hat trick, and as you can see I was warned about leaving the game.

It said if I have any technical issues I should come here, so here I am. Why is it every time there is a promo on your servers turn to sludge and have all sorts of issues? I know you probably aren't able to do anything, but I've lost my time, rivals points and have to complete evo objectives all over again. It just feels. It's just really frustrating and shouldn't really have happened, people in games should have priority on connecting back to ultimate team, and they shouldn't be penalised for something going wrong on your end.
