How did you pay him?

If you used PayPal, file a complaint with them and get your money back.

I _really_ hope you didn't send a check or cash.

And just to add my voice to the others here:
What you have there is OBVIOUSLY two stock pulleys. I have a Code3 on my car, and it is easy to tell the difference between the stock and Code3. The stock is thicker (duh!) and has a chamfered rim (that's like a beveled rim). The Code3 rim is rounded, and is visibly different on or off the car. I could tell immediately from your picture that you have two stock pulleys there.
