Naaptol / Spy Pen 8GB — sending fake product and getting money

I ordered to Naaptol a spypen 8GB (ORDER No.42982) which they offered for Rs.1690/- they gave me option to pay at the time of delivery. The courier man got the money and delivered on 11/09/2009. After that I opened to see the product, it worked not even for an hour. It went off. No life in that. Complained on the same day. When complained through email no response or even acknowledgment. When contacted on 14/09/09 through phone, all are speaking Hindi, when requested to speak in English, one lady attended and asked the order number and promised to send with in 10 working days. Today I contacted them again and asked about it, they say the same version 'it will take 10 working days'. This time, they added that they would ask the courier to collect back the device from me and then they would replace new after 10 working days. I strongly doubt their genuineness. They seem to be playing fraud on me. May be on many more.
