I'm tilted

I'm in bronze. Yes I'm a bronzie, but the people down here are actually so frustrating to play with. People down here don't have any game knowledge, I just had a game in which I was winning lane and if you're wondering yes I did roam, I was fed I was able to solo anyone but my whole team decided to stay mid while the enemy trynd was split pushing top lane with a huge minion wave coming in bot lane, I decided to go bot to clear the wave hoping my team mates will take care of trynd but guess what? They decided to follow me bot lane to take cs no one bothered going top lane and I ended up having go top after everyone started following (The trynd ended up getting to the inhibitor). Later on in the game my team kept on forcing 4v5s in which I the most fed person wasn't there, they kept on forcing these stupid team fights while I was clearing waves (They never cleared waves so I was forced to, the towers were getting low) until twitch was fed enough to one shot everyone including me. Also guess what my team did to counter twitch. Nothing. No one except me bothered buying oracle. This kind of thing happens every game where I win lane but some other lane decides to feed their asses off and I can't do sh** because my team always stays mid forcing team fight while I clear side lane waves. (Also I do try to communicate but it never works they are only care about kills. Most people here also don't realize 12cs = just about 1 kill)
