Consumer Redressal

For my Whirlpool RO Water Filter, I had taken an AMC plan called - RO Comprehesice Plan for MES 6.6/8.5 on 22-01-2013 valid for a year. On a subsequent call, soon after taking AMC, the service engineer replaced the 4 filters as they were not functional. Subsequently, a service engineer had been coming periodically to check the purifier and replaced the pre-filter (charging me Rs.300+ each time).Now in 9 months time, the RO purifier is totally non-functional When requesting for service under the AMC contract, the company service department tells me that all4 filters have to again replaced because in our area the water has high salt content and the company\'s filters are damaged because of this. I have been asked to pay Rs.5000/- for their replacement. Why this sham of AMC by Whirlpool if they are going to charge me each time for the RO purifier . Whirlpool has to return to me back my AMC money and should not longer offer AMC to its RO purifier as the product seems to be a failure.
