Pureit / Hindustan Unilever — Faulty Circuit Board in Marvella RO+UV

Address:

600070

I bought Pureit Marvello RO+UV water purifier on December 2015 for Rs 18, 000. I have replaced the first filter (SF) on September 2016.
On 28th December 2016, I replaced GKK1 filter kit for Rs 1850/ (complaint # C[protected]. Unfortunately, with in another three months ie on 19th March 2017, the machine signaled the GKK2 warning light asking me to replace another set of filters. This time they inspected and replaced the remaining set of filter (GKK2) for Rs. 4000. But, right after the moment the service person left my home, all the three warning lights were started blinking. I have raised the complaint again immediately (Complaint No C[protected] and now they are asking me to replace the circuit board itself which will cost me about another Rs 3200.
I am highly disappointed with the quality of this product and also the kind of service that are being provided to the customers. In my case, if the actual cause is the faulty circuit board, I wonder why this issue did not occur before replacing the GKK2 filter and why it occurred immediately after the replacement. I suspect on both the level of training offered to the service persons and also the cheap third grade quality of the electronic components that have been used in this product. I expect the Hindustan Unilever customer care should take some actions immediately.
