Naaptol / 16gb Spy Pen — Not showing hidden files,picture & recordings..

Address:

Pune, Maharashtra

have purchased a Naaptol product with order number not my memory and have received a faulty and used piece.
The product was 16gb spy pen drive camera which was used earlier as there were some old videos in it.
Also the product was not in good condition and had scratches on it.
When i contacted naaptol, they adviced me to send back the device and would replace the product however on the consumer complaints I am looking at other customers who have experienced a similar product and have not received any replaced goods.
I want to keep this piece with me and would show it as an evidence that this was a cheating case.

I have attached photo, you can check the image and the cd which has all scratches, also another image from the system screen shot of the pen drive having older video which was shot from this device.

The product was delieverd from seller
