Kent Grand Plus Water Purifier — poor service

Address:

South 24 Parganas, West Bengal

sir, i have purchased a kent mineral ro water purifiers 0n 1.12.2009. after completion of one year i took AMC (annual maintenance contract) for each year afterwards. now the current service period is 30.11.2011 to 29.11.2012 which is a full service contract with full replacement of parts. now since last three months a have been complaining again and again. after every complain a service executive comes and checks the machine and and after servicing returns and says machine is ok. but after repeated efforts the problem is not solved. last time the executive told that the RO filter needs to be replaced which is covered under the AMC. but he replaced the same with a regenerated parts not with the new part which is covered under the AMC. problem still persists. please look into the matter.
