[Resolved]  Samsung Refrigerator Model No. Rt23rvms1 / Xtl Double Door Frost Free 230litres — no cooling in the freezer

we had purchased this model refrigerator from Snehanjali Malad, on the 28th May 2008. Since last one week, the freezer has stopped cooling. when complained about this to the service centre ([protected]) complaint no. [protected]. they managed to send the service person. That service engineers said the service charges would be Rs.350 + tax and the gas has to be refilled that would cost another Rs.786. Whereas, when we had checked the rates from atleast four of their service centre executives, we were told that for 230 litres, the service charges would be Rs.300+tax and gas refilling would be Rs.450+tax.
this is like cheating the customers, saying one rate (that too told and confirmed by four executives), and charging a much higher rate. How can we as customers bank on this brand in future? where the service incharge are all cheats. Would like to get the servicing and the gas refilling done at the rates that were confirmed by the services centre executives, at the earliest.
thanks,
