A guy scammed me!!!

contact Steam support so they can reverse the transaction (so you get the items back that you've lost in the trade).

that is - assuming you've both traded using the trade window. if you've traded outside of the trade window, you've just learned a valuable lesson and you should move on.

Contact support and post it in SteamRep :)

well ask the support because if you traded it in a trade window they could help giving your keys back but if its a key youre out of luck .-.

Contact Steam support, they will surely help you.

He took back the money which used to pay the game to his paypal account. That's how.

You will get your items back IF you traded the items together through Steam.

As others already said, if you traded via official Steam Trade, you are covered and will eventually have your stuff back (you will probably have to wait a couple days).

If you traded outside steam, you have just thrown stuff down the toilet.

You seem to have gun doofed hard.

Well, as stated: If you traded through Steam window, you will be mostly fine. Otherwise, remember: If a offer is too good to be true, think twice.
