Did you bought this on ebay? If you did, you need to call your credit card company and ask for a refund. They will deal with the rest. There is a close that prevents these kind of scams if the goods don't provide the claims of the seller.
If the guy don't answer the phone, go pay him a visit. Don't count on the police for these kind of scam and forget small claims court... a money pit as well...
I got ripped off on ebay while buying an Athlon 64 FX... the guy never send anything and forced me to pay via Western Union... it was in 2002 when Paypal was not really popular and ebay policies was crap... not that different from today, but at that time ebay was offering really nice deals... now it's nothing else than a scam site.
