How do you guys break the "bad team mates" vibe?

So I'm currently on a four game losing streak (ranked). There was one match where my game play wasn't at it's best, but generally my game play is consistent.

Anyway, what I have noticed is that on each of those teams I have had 1-2 players constantly typing, flaming, and/or spam pinging people for small mistakes. There has also been someone in each match who gives up after 1-2 deaths and proceeds to feed and mentally check out. To top it off, no one agrees to FF so it's just 30 minutes of getting stomped while waiting for the enemy team to end.

What do you guys do to break this up? Swap to ARAM, bots, draft? It gets tiring playing decent and beating up my lane opponent just to find the rest of the map in chaos. I'd rather not keep this losing streak going because of the types of team mates I am constantly being placed with.

I know we all go through this, but I'm curious what other people do to help this. Thanks.
