Can Someone Teach Me How 2 Ekko?

I swear to zeus I have tried SOOO fucking hard to try and make him useful, but I keep getting shitted on every single game. Every single lane, and every single freaking queue I go 0/8/14. It gets me on tilt and pisses me off. Someone tell me how to play this skinny hoodlum and what to do if behind because I am literally about to press refund on this guy.
