Playing duo queue is the best...you run into the classiest players

Get into duo queue and champion select goes fine, I get adc and have a leona supp. Seems like the game is going to go fine. Until leona afks until minons spawn then runs into lane and afks by tower for around 10 minutes. I cant 1v2 a ez and taric so my lane is pretty much lost. Leona come back, things may be looking up, nope. She plays super aggressive and dies almost every time in lane. I call her out for afking and she denies it ever happened. Meanwhile the guy that begged for mid is feeding a kass someone failed to ban, and after it all my gf gets demoted. Its bronze but still it sucks getting stuck with the trolls almost every game. Sorry if I'm ranting, guess I'm just hoping for any advice out of this hell -.-
