Fut finals

I was in a game where my opponent rage quit very early on

 I'm not very good at FC so every game I win is a blessing. Now once he rage quit my game was just in a frozen like manner. I couldn't move anything and it didn't bring me to the screen that it does when you win. So I decided to close the game and go back in. Now once I was back in the game I was met with a message saying I didn't finish the game which clearly I did since I won and he quit. I wanna know if there is anything I can do or I just have to deal with the fact that this game has way too many bugs.
