Riot disgusting behaviour

I played with 3 of my friends in the weekend. during one of the games 1 of my friends had problems with his launcher. so me and the second friend decided to get in a game until he could get his problem fixed. during the loading of the game the friend i played with had bad internet and disconnected and the third friend got his client fixed.

After logging in the game i told the team we were premades and had a problem told them we want to remake. 2 of them said no. so i did the best thing i could think of and that was feeding. after a few minutes my friend reconnected and we did it together to end the game faster. after the game ended the game after that i got a message that i got banned FOR 14 DAYS!

WHAT THE FUCK???

this was a normal game, no one lost any points. i never do this this was the first time, and straight up i get a BAN?? was this ok to do? i dont know. but it was the best solution we had to play together. after that i sent riot a support ticket and told them what happened and they excused it with: (KASIIM) "If your teammates refused the remake vote, this means they wanted to play the game, but you took that away from then and ruined the experience for them, so this makes your punishment fully deserved".

and for that i say FUCK YOU! what about MY EXPERIENCE? why would i want to help them?? a friend of mine was waiting, and another had connection issues.

what i did was ok? no. but to give me a straight up BAN?! give me a warning, put me in a 20 queue or something. dont just ban me like all i ever did in this game was to feed. espeacially if its the fist time doing so, and especially after spending money in this account.
