Getting Ripped off online

[PeTr0]

I sent someone a moneyorder for a part that i purchased off the corral.net classifieds. The guy seems real cool and talks to me online about installing the parts and numerous other topics. He never has the UPS tracking number handy and i am starting to get the point that i am not going to be recieving these parts. What can i do...I am pretty pissed. UPS said they cant help me find out if the package was ever shipped without a tracking number...which is ridiculous.
