Kent Ro Systems - Kent RO worst Serices

Using Kent RO water purifire, on every service equipment has been changed which is chargable to the consumers. From last three months RO purifire is not working although bought an insurance policy worth ****/- for the same. Company technician visit premises and said ****/- more need to change equipment. On every service the main moto is to sell the equipment resolution of the issue still not done. Fa mily members falls ill by using the water from the product which is the primary concern to me. The company doesn't even care about the health of the consumers.
