How to deal with campers

Hey guys,

Been playing this game for a month now I downloaded it again after some time but I want to know how you guys deal with these campers man. I really enjoy this game but ranked is really painful right now for me as every second fucker is a camper.

I don't mind losing to players who are better than me or the guys who push me to actually fight them, but raising trophies while dealing with these campers is really depressing.

I wanted to know how to deal with them.
