How are you supposed to deal with an inting team in low Elo normals?

I say low Elo because I assume normal, unranked games are lower Elo. I haven't started playing ranked yet. I'm gonna be honest, I'm pretty tilted...I was on a 9 game winning streak, about to pop 10, when I had the worst team ever. I was playing Kha'zix jungle all these games. The warning signs only showed themselves when they were too late. Soon as the game started, I asked for a leash from top. No response. After ages I finally get 'Oh huH sOrrY dude was ripping the bong no idea what I'm doing lolz". Then mid lane goes "dude sameee." It would've been such an easy game, the other jungler was an IVERN who went 1-9, I took 3 dragons and a rift, and it looked like we had the upper hand early-game. But then the enemy mid Katarina got super fed off our stoned Mid and started one-shotting everyone (her final score was like 21-10). Similar deal with the enemy top Urgot. Needless to say we lost. The next game was even worse, literally every one of the lanes went like 0-4 or 2-4 at best...

/Rant over. I should also mention there's always the danger of trolls or afkers on top of that. How are you supposed to win if you have an inting/afking/trolling team??
