Ban System - Please read Riot

So I was going to be playing bot lane as Jhin today (11/23/17), and when I got to the point where I was going to lock in my champ, I switched to Soraka Accidentally. But I figured screw it! Let's have some fun, It's only a norm. At the time I did this my whole team instantly started being toxic to me and taking every chance to hate on me. I get in game and as I said I was the adc role so I thought I'd go adc. My jungler thought to make the game hard for me in lane and I didn't care. I had the mentality that it's just Draft and not ranked. So my jg inted a kill, I'm csing with this Twitch beside me that went an adc because I was "adc Soraka". He inted two kills because I was "stealing" his cs. The game goes on and the whole team is telling the other team I said all these toxic things, which I never said any. To get the other team to report me. At the end of the game I reported the four players that were extensively toxic towards me. And I'm guessing that everyone reported me for something and I got banned on the acount named "Oceans are blu" My question is, does anyone actually check for these things? Because I didn't do anything wrong. I didn't feed or int. In fact most of my team had more deaths than me. And I wasn't toxic at all. I was defending myself in a calm manner. Is there anyway I can get unbanned? Because this is totally unfair that I got banned for something I didn't do.
