Getting an S but still losing

I really dislike how hard it is to climb the ladder from such low elo's. I continuously win lane and receive S grades at the end of my matches, but still lose the match because a different lane fed. I wish there was a way to get out and play with people who don't feed and who are willing to adjust around what they are doing wrong. Thats the biggest problem with bronze, the lack of communication in chat and willingness to accept that they are losing the game for everyone else. ugh stuck here forever I guess.
