Chat: N/A
Trade: (Warning, German)
Description: He started to ask for the unusual Team Captain. I traded him. He gave around 3 weak unusuals, 50 stranges and 5 keys. I went shortly AFK while I was ready to trade, but joep has reduced the amount to the pic shown above. Therefore, I messaged him and asked if I can have my unusual back. He refused. So I called my friends for help. Same result. Then I called 2 experts on retrieving items. But their accounts have been hacked. Therefore, I can only hope for Steam Support to help me.

I've also filed a report against the same guy which could be found here http://forums.steamrep.com/threads/76561198044338204-joep-fernando.11289/
I hope he gets marked soon before he scams more hats from inexperienced players.

Already marked, adding notes about this case. Thank you for the report.
