How to deal with Bad Supports as ADC?

NOTE: I am no god at ADC, i main it, i am not the best, but im not the worst. I do not claim to be some pro ADC player that is a know it all, far from the truth.

Was just playing a Normal game, Had what he claimed to be a ' 2nd time janna, new to support ' I can deal with new supports, but this wasn't just a new support playing a new champ, they seemed to be brand new, although i haven't looked at his stats or anything, first thing he did was rush bot and get killed within just a couple minutes of the game, Even new supports know not to literally push the bush and basically flank 1v2 at the very beginning, Obviously died giving them first blood, I dealt with it probably the worst way possible, i called him a troll, I said even people new to sup and champs understand not to do what he just did, then he decided that the best option was to not play sup, he started stealing minion kills, Went into jungle often, basically started doing there own thing, Was playing ultra aggressive, Was taking on fights he obviously couldn't win causing me to go into the river and attempt to prevent my sup to die, which i did successfully sometimes.. shit got to the point where if we were in a fight 2v2 bot and we were retreating back to the turret he'd just stand there and watch, had the ability to heal, attempt to stop or slow down the attackers but nope, Just stood and watched, after i died (at this point anyone witnessing it would of called it a 1v2 rather than a 2v2 considering he literally stood and watched.) I decided the best option was to stop supporting my support and Alt F4'd.

I can think of only 1 time he actually helped was healing me, but he i think he meant to only heal himself i just happened to be next to him.

How do you deal with obvious troll supports playing aggressive and not at all supporting.
