[Resolved]  Whirlpool Double Door Fridge Ff400 Elite — AMC does not cover part and very bad service

We purchased a double door in 2004 and took AMC in 2006 through Whirlpool authorised agent not only for the fridge but purchased a 7 year garuntee stablizer also. The fridge stopped functioning in April 20. 2009. The service engineers firstly cannot point out what is wrong immediately. One man says its the gas the next says its some other part the third person comes and replaces the compressor. They charge us Rs. 1200 for a dyer (please note this is not a plastic part nor a glass part ) which is a part put at the back near the compressor. When we took the AMC in 2006 we were told that all parts were covered except what is in the front of the fridge ie the plastic components, glass components etc.
No senior in the organisation is ready to take responsiblity or attend to my calls. The boys at the call center keep saying you will get a call but no call comes through. Now the situation is that the stabiliser which was working till the engineers came is also not functioning. On 23rd I lodged another complaint for the stabilzer but its still to be attended. Its shameful that a company like Whirlpool has appointed such useless services personnels - I am at a loss as to what to do and how to take action against this.
