Players Who Lie When Reporting

So I was in a game recently where I was playing as Sivir with a midlane Ahri and a Zac support. In game the Ahri got firstblooded by the enemy jungler when she was pushed up in lane. After 4 more minutes she died again and I died twice to the same jungler. She randomly called me out for being bad, and since I felt that was unfair, I replied something like "i think it's unfair for you to call me bad, we have the same amount of deaths and i'm 40 CS up on you at 12 minutes". Looking back, I realized making it a competition may not have been a good idea, as she instantly went all "aww boo boo but I have a kill, that puts me up 20 cs so I'm only behind you a little bit". For the rest of the game, she was acting very condescending to me and Zac joined in to all chat basically just saying "report sivir very toxic" and "shouting n-words at us the whole game, bad adc". I understood why they may have thought me to be a little toxic, but I never swore and when I talked i tried my best to be polite and diffuse the argument. After the game Ahri and Zac both reported me, Ahri because I was "feeding, toxic and retarded" and Zac because I was "shouting and flaming us with the N word all game". Honestly both of those to me are untrue and it just grinds my gears to see people randomly reporting a scapegoat (falsely) when they're tilted or they did badly. Anyways thanks y'all for reading this rant and if you've ever been in my position give this thread a thumbs up and get it out there :)
