What are my chances of getting banned

For some reason Riot has this system where you get a duo in ranked and then even though you report both of them for inting/flaming you get them again in the next game. Well we had some words but nothing ridiculous in our lobby when we got re-queued in next game... they dont leash me jungle (they are bot duo), fine. It didnt matter because I was yi. We're doing decent in game but they still talking crap whej they die blaming me or whatever. Long story short my freaking power just went out from this big storm on the gulf but it isnt even raining atm. Really aggravating, but I absolutely know these guys are going to report me for leaving the game/afk. Seriously it's going to be depressing if i end up getting banned for that as it is not intentional and i absolutely dislike people who quit games for any reason. I've never done that and never would do that despite how far behind or how crappy my team mates are treating me. What do you guys think? Will I get punished for this?
