riot just wasted 77 min of my life

in 2 games because of a duo who keep playing and feeding and one of them was elo boosted so he played like complete trash and fed both games while i kept the games alive for 40 min each to lose only because its basically 3v6 due to the duo. I already told a riot member but fuck its goddamn annoying to waste so much time for nothing because you cant detect these easily found boosters. (flipped summoners was diamond now feeds his ass off in plat 5 mmr when hes gold 2)
