Description:
I traded with "A.looking csgo" and I've got "MW3" and then few hours later, I traded the "MW3"
with "HARDCORE"
And, today "HARDCORE" said the "MW3" has been disappeared.
What should I do??? I've reported to steam, but I need an advice. Can I(or HARDCORE) get back "MW3" ?
I don't know really... I need a help.

Yes, report it to Steam with a support ticket. http://support.steampowered.com

Adding this to the guy's rap sheet- thanks for the report.
