Anand India — handsfree android wrist mobile

So i bought The product Handsfree Android Wrist Mobile by watching the ad on my TV. When I got it it wasn't working at all, I did everything that is been said but nothing happen, then I returned the product by calling them, and they gave the address and i send the product on that address. But its been 3 months, I didn't get any answer from them, i didn't get the money back nor even the replaced product. i tried many time contacting them but they refuse with many reasons and say we will look into it and nothing has happened till now, it is now coming to the end of 3rd month.
