[Resolved]  Kent RO — unfair/unethical dealing by service person

Address:

Ghaziabad, Uttar Pradesh, 201019

I am a resident of vaishali, ghaziabad, uttar pradesh
Recently i faced a problem with my kent ro, so i contacted the customer care at 14th july 2017.

They sent a service man who began inspecting the ro
First he told us that the filters were not working. We told him that they were replaced recently. Then he said that the motor was not working, which was working fine. Then he said maybe the membrane was broken.
He told us that he has to replace the parts and the bill will be near 5500/-
Further he recommended for an amc worth 6500/- (Rs 5000/- rate on internet)

We suspected that the person was misleading us and try to replace components which were working fine so we sent him back and called another mechanic to check the ro. He found that both the components motor and membrane were functioning well. He found another small component worth rs 450/- which was not working. Now our ro is functioning properly

How can we trust kent ro service?
Are your service person trained adequately?
Do you instruct them to inflate bills?
