[Resolved]  Godrej Fridge — defective fridge sold to me

I purchased a new fridge from Vijay sales but they gave me a DEMO piece as another was not available.The defrost door and vegetable tray were already broken down at the time of purchase. Vijay sales changed the veg. tray and Godrej changed the defrost door;
But the freezr was not working when I started the fridge. Godrej serviceman sold me some Frostfree for Rs. 850 saying all new godrej fridges worked only with frostfree and therefore godrej was manufacturing it now. But the componant was useless and when I complained to the manager Mr. Sahil he changed the defrost button and thermostat and my freezer could be used So I was cheated of Rs 850 .
After that the light came off and the main door of the fridge started getting disfigured, By now Godrej has changed the main door but the magnetic connection has become weak. The fridge is still in warranty but is behaving like junk. I have sent several reminders to the company to give me a fresh piece but they are not yet responding. PLEASE HELP
