Joke of a game!

I’ve just been playing fut champions and I was drawing 4-4 and in the 90th minute I score to win the game but before the match fully ends the opponent disconnected and it results in my game disconnecting also didn’t think much of it till I go back on to see that I get the dnf message and I check my record and it gave me the loss !!! What is genuinely wrong with this game even when you win fairly you still lose ??!!
