A premade 4 men team reported me and RITO punished me

So i was first time playing as Kalista and i told my team to play passive and help me to learn how to kalista... everythings ok right? Well after my nautilus support killing spree, i told him to not ks me, because i needed those kills. no big deal tho... My only 2 rude comments were "come on guys it is idiotic to no group up" and "you are not idiot, you know i need you (nautilus) to use my ult" AAAAND THATS IT... my entire team started to ask the enemy team to report me for harrasing, for being rude, for feeding (my score was bad, yes, but that wasnt my purpose) and everyone agreed to report me if my team a guy in their own team... WTF!!?? i got 8 reports that game i bet that was so excesive.

btw and after play 10 games with chat restrictions (sigh) im still unelegible to win key fragments or hextech chests (WHY?????) for how long? i think thats unfair. what do you guys think. Im not whinning, i just think that should not happen

Sorry for bad english
