You have been scamed. If you still have screenshots of the chat, report his on steamrep.com and use the chat messages as evidence. The offer was too good to be true, as a bundle game is never worth that much. You can negitive rep him and post a scammer alert on here. Other than that, theres nothing you can do. It happens, but you just gotta keep on your toes. Also, as word of advice if he has less rep than you, HE goes first. Not you. Good luck.
to be honest ... a key form = uplay ... those ain't worth much, I can see a trade happening to be honest.
If it wasnt worth all that much, why would he ask for 10 dollars plus another game?
The bastard changed his steam name, blocked me, and all I have is our conversation, copy and pasted into a .txt file. Is there any way I can get my game back? :(
Quite improbable, but the best you could do is to report him to warn other users, so he won't scam anyone else... Try to find him by this method, probably you won't get any result, but maybe he is a dumb scammer.
That might work but it might be better evidence if you actally have screenshots of the conversation
I went to go do a trade with someone named "DarkSpirit" when he told me that he would trade me Far Cry 3 blood dragon (in key form) for my killing floor humble bundle key. When I gave him the url, he unfriended me, used the code, and went offline! he robbed me of money, and didnt give me the game he promised to! Is there any way I can get my game back, or the game he said he would give me? This is extremely aggravating, and I have been robbed of $10!
