My name - susanta kumar basu. My customer i. D - [protected] have two water purifier - - one is integra 7 and the other is hiflo both the units are on active annual maintenance contract and at my resendence at - flat no - n3 plot no - 245 block no - a lake town kolkata - 700089.
The integra 7 have been giving trouble during last one year some times the u. V system fails to function some times the printed circuit board gets burnt out. In both the cases the co. "s franchaisee people (Having least technical knowledge) after repeated pursuation replaces the defective unit with another defective unit being repaired earlier. The u. V system of integra purifier is the most important part fals frequently say at least six times during last one year of contract maintenace. Starting from july, 2014. They never replaces the this vital unit with a new one to relief the customer compelling the family members including the childrens also facing health hazards because water is never fully purified or bacteria free due to failure of the u. V system, again the printed circuit boars which is the heart of the whole purifier unit gets burnt out at least thrice during last one year. I asked the franchaisee people to instal new p. C. B but they refused. As regards high flow purifier the same condition arises its p. C. B being burnt out. The franchaisee people does nothing. Recently the co. Has introduced digital signature through mobile after service which i had refused since there is no intimation by the co. Circulaing this notification. My question is why this sustem?
