wtf league kicks me out

LoL keeps crashing on me in games right after I get out from time penalties and I keep getting them. Like what happens is I get a time penalty for one afk because I was very cold (I couldn't play i was freezing to death, i got sick at that time) and then 5 minutes for 5 games, then lag kicked me out and made me wait 10 minutes for 5 games. Now lag (on your end my internet is fine) kicked me out AGAIN(ffs) now i have to wait 20 minutes for 5 games. 100 minutes wasted instead of league of legends games. i keep telling my friend to tell them not to remake because im reconnecting and they remake ffs please find some way to fix this. am butthurt as hell
