People quitting at 0-0

So 79 mins into a champions game its 0-0 I'm through on goal the player takes me out gets a red card then just pauses and quits the game then I'm not rewarded at all and have wasted my time playing that 79 mins I know they loose but how do we not get the win after a someone quits especially that late in a game honestly how this is still a thing is a joke sort it out please
