If it is in the US, you can try contacting the local police. They probably won't be interested, but sometimes they will cooperate. If you are a UPS customer, you might contact their fraud department - I've had UPS allow a policeman to make a delivery, and then arrest they fraudulent customer when he signed for the packages. Fraud is a significant expense for UPS, and they might have more muscle in getting local law enforcement involved.

Theoretically, the Secret Service is responsible for mail order/credit card fraud, but it's pretty hard to get them interested unless it's a major scam.
