Inefficient Customer Service Kent RO Systems Ltd

This is to formally raise a concern with requisite stakeholders in Kent RO Systems for the suffering and distress caused by the Kent RO team in Bangalore. We've been victims of there service centers and feel cheated.

We installed the Kent RO system installed 2009 and it seemed to work well for first few years. As like any system, the parts were refreshed to maintain quality of the service in this case - good, drinkable water.

It was until this year that we've been barraged with series of part replacements and that's part of the pain on behalf of Kent RO services team.
First, every few weeks, either the quality of water or a part was required to be replaced - some system indicated while some - JUST DON'T KNOW!
Noone who will visit us will tell us what will follow next and not do a comprehensive job.

What makes it worst is the attitude of the people in service center. We complained again that the quality of water is not good and called for an Engineer. The Engineer first was a clueless prick who kept toying with the equipment, called multiple went away and said he will return. Thereafter without a logical reason stated a part worth 2k needs to be replaced. We complied and okayed.

But that wasnt it. The quality of water on a meter scale which Kent has should be in the vicinity of a number 65. The enigneer leaves at a reading of 90+ and tells us it will be ok. The system wasn't ok and in next few days the quality deteriorated. We called again.

The same duffer engineer came, no explanation and assured us to fix the problem. When asked to test the quality of water, he chose to be oversmart and drained whatever was in the container. When on persistence we asked to check the reading on the meter was a whooping 300. He didnt have the guilt of a dying man.

He goes away, with a work around as the water is still not the same from Kent system to what we are used to consuming.
We called service center to complain and we were told that someone will visit us. We insisted on a new Engineer and they assured somebody will visit and its been over 3 days and no one from Kent is here.

This is absoutely unacceptable. Kent has to take care of this and I need a detailed explanation as to how do they intend to address this problem and a committment.
