Description:
So there is no screenshots of a trade window or chat, cause that's the first time i got scammed. So, that's what happened: i have tf2op post ( http://www.tf2outpost.com/trade/4832321 ) where i'm buying s. grenade launchers for 4 keys. There was a guy, who's added me and asked if i am buying them. I sayed yes, but asked him to wait, cause i had another trade at that moment. He asked me to hurry up. Then we got trade and he put his s. launcher. I put 3 keys and 2.66. Then he asked if i can replace my 2.66 metal with a key and meanwhile changed s. launcher with a stock renamed one, which i did not noticed, and immediately deleted me from my friends list. At the time i thought: that's really strange, but whatever. And accepted the trade. So here i am, with 4 less keys and 1 more stock grenade launcher :'(.
Sorry for my english, sincerely Flungloaf =)

I would like to point out that he tried to do this to be as well. I have a chat log. But when a trade is canceled it will close automatically for the other person. So i have no screenshots of the actual trade.
Here is the Chat: http://i.imgur.com/sBoeO.png
Here is the profile: http://i.imgur.com/bpO3P.png
And I would like to point out that his custom Url is: http://steamcommunity.com/id/dlawhdgh/
So Basically we had the exact same thing happen, I was just lucky enough to notice and so we had a different outcome.

I've just got answered by STEAM support, that they will not give my keys back . Hope i'll get this guy here atleast

Well if you have no screenshots, we can't process it. Sorry.
