Logic

hello there community ! i need help in this 1 coz im being in big trouble not finding solution for this problem. here is the thing, im cho , theres kaisa with me bot , vs syndra rengar in urf, min 4 kaisa's score is 0-3 ,my score is 1-0. At min 5 kaisa's hp is 50 hp i pinged to fall back to go base and come back with canon , she kept pushing diving till she died 0-4, i said "wtf r u doing", she replied "stop flaming" me .talon from our team palying top agreed with kaisa and said that im so toxic, i stoped talking , enemy syndra 5-0 score started snowballing eveeybody 1 shoting all of us, my score was 4-0 now its 4-4 , im playing defensive , kaisa keep pushing and blaming me for not helping and having score 2-9 , talon agreed reporting me for zero help and flame toxic , i started help by pushing like kaisa , now i have score 4-9 , kaisa 2-14, game ended my team typing , report bot for inting 2-14 and 4-11 scores. i got chat restriction coz i pointed out for kaisa to stop inting and dive with 50 hp vs feded rengar and syndra , and she kept going to the bush so rengar 1 shot her, riot system banned my chat coz in the records there is sentence saying i typed " WTF R U DOING , STOP INTING."

My question is what does other players doing if u were in my place , this game logic says i must not type anything is chat like stop inting u r already 0-4 in 3 min? why there is chat box than if its forbiden to talk?? what should i do if my laner is 0-4 ? should i go in dive like him to help and get 4-11 score like him? shall i step back and watch so all team say zero help ? im so freaking confused what to do not to keep getting bans, seems like whatever i do im getting bans anyways.

sorry for the long story but thsi is only 1 game and i have saved the game in my highlights, if u need more problems theres like 20 and more in my highlights saved games shows whatever i do im wrong some 1 teach me the correct way to get out of this .
