I had purchased 310 ltr Whirlpool refrigerator on 30-APR-2006. Since purchase I am not happy with cooling of this refrigerator,earlier cooling was low but now it is totally gone. I tried to contact whirlpool service center and I got a reply that they would charge 390 Rs for inspection of this faulty refrigerator. I don't how such a big brand makes such type of Appliances and instead of rectifying the fault they want to charge customer.
