[Resolved]  Videocon DVD+dth — replacement payment

I purchase videocon 17 inch tv in scheme from asian radio house, sangli on 21-dec-2007. In this scheme with TV, dvd+dth box is given free. But dvd+dth not work properly. It fail after two repairy. So asian radio house says to replacement of this product.
At time purchasing sell persons in asian radio house sangli tell the price of (dvd+dth box )Rs.3390/-. Now they said to us we give only Rs.2000/- and other difference is paid by me.
If company wants to call back all products(dvd+dth box) from the market. Then it is company responsbility to give the replacement of product, free in warranty period.For this perticular (dvd+dth)product several customers complaints are recieved to the service center and almost all product are faulty.
