First Game First Banned Of The Day (First Time) 14 Days Banned

So I just started my first game And I got Adc and trying Ezreal for the 6th or something since I just got him and wanted to practice him. So finally loaded in to champ select One of the people didnt even call/say anything so he got autofill as sup, so this person went Camille sup. Just a few minutes in the game she just started stealing CS so im like why do U keep stealing cs and and she was like I need it then I told her dont play sup and go top instead. I was totally done I cant farm, she kept stealing cs, and I was finally mad told her have fun bot so i went to jg to farm instead, and this has happen now getting banned and then for the past few days where I keep getting queued with Toxic people. Also my Mid (Katarina) and JG (Nocturne) was arguing the whole game and just flaming one another since Kat was losing to TF she keep wanting/spam some ganks but then our Jg was losing and feeding to the other JG already and keep saying Yi is trash yet his losing. I like how Riot only showed my comments instead of the whole team chat, I can watch the replay and ill post it again unless Riot watch the replay. I know i called some people stupid and %%%s and told them to stfu since they cant stop spamming and talking like they are some pro-players but like I didnt even tell them to kys before people just type kys every seconds and they get no banned like wut. Also when were about to lose Kat keep saying use your ult properly like i cant one shot the enemy team since they are so ahead so i just ult clear wave so they cant push faster and Noc just keep talking some dumb sht thats when I was officially done. If I was the only one who got banned omg im done with this game https://imgur.com/a/fOFx2cz TY RIOT Now im gonna missed the missions for MSI
