Description: I was talking in voice that I was trading two keys for a strange rainblower, this guy starts up a trade with me, the first time it had an error. the second time he started the trade it went through, so i placed my keys on the table thinking that I was going to get the item I wanted in return. So he gives me this strange counter, part and a rainblower and gives me the explanation that it was "self-assembly" after 3 seconds I call him out on it, as the others tell me it was a scam and repeated attempts at using the item on the rainblower I received, failed. Itsapwell insisted that it worked and disconnected from the server when the others started saying scam.

the chatlog got pushed up while i was doing this report, all i have is the items that i traded for...if you could please reverse the trade.

Do you have screenshots of the chat?

im afraid not, i kind of gave up on getting it resolved though. my stupidity is just another learning experience. if i could get my keys back that would be nice, but all in all wishful thinking.

Unfortunately without proper screenshots, there isn't much that can be done. I hope you do indeed learn from the experience.
