Issue with Opponents Quitting and Not Receiving Wins in Division Rival Games

I'm facing an issue where players are quitting during division rival games, trying to get free wins by playing with friends. In my last two games, my opponents quit after I scored goals, but I didn’t receive my wins. This has been happening consistently, and it’s affecting my progress. I need help to address this problem. Please guide me on how to get my wins and prevent this from happening again.
