This guy traded with me while I was playing a game. He said he'd trade his Kantusa for my Denizen. I didn't get time to think about it and I immediately accepted. I rushed to put the items to trade. He also added some items and begged me to add too. He put some items and was ready to trade but then he quickly removed the Kantusa without me noticing and as I clicked the make deal, I saw the Kantusa was missing. I tried to cancel the trade but it was too late.

Evidence of trade.

Could you please provide:
a) pictures of chat where the agreement was made
b) pictures of inventory history showing it in the Steam browser for the entire day
I have marked this thread as need more info.

a) The chat agreement of the deal got flooded with my repetitive begging. When I checked back our chat, I saw it no more
b) http://imgur.com/YTtoEUW
(PS: the trade between my brother "Eh_AnU_ShaBu_Pa?" and me is simply the transferring of my items from my other account, in case you're wondering)

This is all I got, just me begging to him to give it back. But then I realized he blocked me. That's how slow my brain was while playing. http://imgur.com/LiGNymZ

What else should I do, sir?
