Screenshots

unfortunately lost the first half of the convo by accidentally closing the chat window. here is what remains


He then sent me this a while later, not really sure what he was attempting but he didn't remove the -rep or give me back any keys.


Description

User claimed to be selling Payday 2 keys for 4 TF2 Keys each so i agreed a deal of 2 copies for 7 TF2 keys but was trading through an Alt - his current account was not trade banned so i did not think it was a scam at that point. He got me to send him 3 TF2 keys and then sent me used keys for Forge Starter Pack and Zeno Clash, and when I pointed this out to him, refused to send me back my keys, saying he already given them away, which was a lie. When i pointed out I could see them in his inventory, he set it to private.

He also did the same to another user, further details can be seen on this thread on steamtrades:
