Game Issues

Um well. I dont know what to do here. My league game literally just froze durring the match and I couldnt move or anything so I restarted my computer and got back into the game, We ended up winning, they had a sion who was constantly just feeding the whole time on purpose, and then as soon as I finished the game I got leaver busted and now I have to wait 20 minutes for 5 games. . . are you guys able to bypass this on my account or something because I clearly dont deserve this punishment at all.
