I work for a Caterpillar dealer with over 10  locations. This number calls all locations and asks for the parts department. I don't think the caller has ever even heard of manners. This is a scam. The caller orders very expensive parts and wants them shipped to an address, but has no intention of paying for them. If you're unsure, tell him someone has to physically come in and pay for the parts and I guarantee the jerk will hang up on you.
