fraud online rackets

I have ordered 32 GB German SPY PEN CAMERA on 17/12/2012, which is costing Rs. 1970/- (OneThousand Nine Hundred and Seventy only) to this effect, I have received a courier from the GATI (with the DOCKET NO 487301546 Dated: 20/12/2012 from "ONLINE STORE SHOP 3260/3, 1st Floor, Sirkiwalan, Delhi - 110 007") after paying Rs. 1970/- in which I found only A USELESS PEN CAMERA + Fix it Pro (Gift) then I tried to call the mobile no. 9716921567 (which is used for my order as well as it is available in the website http://www.pencameraindia.com/32-gb-spy-pen-camera.html for online ordering of products) but no body is responding with the said no.
