Riot Impersonator

This Ashe is a player I've recently played with. Long story short the Fiora and fizz on my team were toxic so I said in the after game chat "please report Fiora and fizz" Then the enemy Ashe then began to call me trash, kid, useless etc... Then he tells me he's reporting me. I then proceed to tell him "reporting me isn't going to do anything, if they have no reason to, they won't ban me." Then he tells me he works for riot and that " when he goes to work tomorrow I'm going to get banned". I tell him that I don't even know how to answer that statement. Then he starts saying threats to my account.

                   I get on the next mourning and I haven't seen a "A player you recently reported has been punished" deal. Please take care of this. I have photo proof of all of the text, but I don't know how to post photos onto this using my IPad. Please fix this problem reds. I would greatly appreciate it. 

If you need the proof, message me on my league account and I will give you my skype. Then I will give you the photos through skype. If this Ashe has been punished, I would like to know so I know he didn't get away with it.
