What happened? Description:

Today I lost 6 keys (scammed), I was on a trade server, and I posted an anoucement that I buy all things of the others.
Then, Napa sended me a trade and offered me a STRANGE FESTIVIZED SCATTERGUN, and he sayd that the price was 12 keys, fake, the 12 keys price is for the FESTIVE no FESTIVIZED scattergun, he offered me 6 keys, and I thought, lol, okay.
I never though it were a second edition of the festivized, the festive, then, he scammed me, today I lost a whole year work. I tryed to communicate with him, and like is normal he was telling me that he don't scammed me.
Here I have screenshoots, please help me.
I don't finded the Festivized because there no apeared when u search fesetivized strange scattergun you see the first listing the fesetive.​

Provide Evidence:

The evidence are on the screenshoots, and my inventory. In the screenshoot you can see my last trade. The FESTIVIZED, for my 6 keys. Also I show the current price of the Festivized and Festive.​
