Can I get banned for this?

So I just bought Rakan on this account and then my teamate decides to ban Rakan so i go Rengar support. And then the whole team is just getting mad at me because die once at the beginning and they say im inting and then the jungler says im trollling because I dont have sightstone and they just keep on saying "REPORT." We FF and i go 3/6 yet the whole team is also negative and they act like the whole game is my fault its just frustrating to deal with. Can i get reported for playing rengar support just because my teamate decides to ban my pick?
