Kent RO — Defective product/Quality not expected

Address:

ananth nagar, ecity, phase2,bangalore

I purchased and installed Kent ACE on 23/03/2020. I am staying in electronic city, bangalore and since the water is not good so I go for a good filter and after checking many I decided to purchase Kent ACE. After few months it started giving issues, sometimes not filtering, some times all water goes by waste pipe, sometimes motor is not working. With in 1 year I raised service requests more than 7 times and their engineer comes and fixed that. Even it was under warranty, they have charged me. The worst part is they suggested to install a pre filter which costs arount 500 rs in the market but he has charged 1200. Now again filter is not working and their engineer is asking me to change all filters and charging 4000+ since 1 year its completed.
