CS-GO Scamming

I've been scammed yesterday for 50$, I met him on ebay, but my Paypal was not working there, so we agreed that he'll put an item on the market worth 50$ and I'll buy it, and then he'll complete his part of the deal, when I bought it, he gave me the account info, and he said "Waiting for code", the Steam guard he meant, to unlock the account.

Then.. he stopped answering me, at first, he sent me a trade link for an account, I added that account, turns out, it's not him, the guy said "I'm a friend of Toney's" .. then, the guy blocked me, after Toney stopped answering, I went on the guy's friends list, found toney's profile, no use.

Anyone wanna assist get back at them? :3
