Proving Innocence

So I recently had chat restrictions placed on my account after a game with someone who decided to be salty. Instead of them admitting to making a mistake - which I pointed out nicely - they used vulgar language and verbally attacked me. Now I know people can lose their cool sometimes, but after the game, I reported them due to them threatening to report me for no particular reason, as well as the verbal abuse. What happened after the game? I got restrictions and they - as far as I know - did not. Is there a way to prove my innocence as I feel I've been trolled by someone abusing the automated system? Also, I'd like to point out that I get honoured for being friendly often. I was even honoured for being friendly during the game that got me the chat restrictions. Two games later, I got honoured again. So I feel I've been cheated of being able to communicate with my teammates when pings aren't enough, or I wish to encourage them with "gj" when they make a good play. Any help with this would be greatly appreciated, thanks.
