Something that sounds too good to be true usually is. People are selling CS:GO invites for $80-100, but you offered Dota 2 + the daily deal game.. you should have realized that only a scammer would offer to take you up on it.
You may read this and think this kind of comment doesn't help, but most of the time you can sniff a scammer out before you get scammed. Are they going along with everything you say too easily? Are they in a rush to complete the deal? Does the deal seem too good to be true? It's as W.C. Fields said.. you can't cheat an honest man. Don't let eagerness about the deal cloud your judgment...
Just my two cents. Do be sure to follow others' advice and report him to Steam, but it looks like that is a dummy account used for making deals anyway.
WHY YOU TRADED WITH A GUY, WHO HAS PROBATION STEAM TRADE STATUS? AND WHY YOU GO FIRST?
your fault for being scammed -.-
