Eureka Forbes — Faulty machine installed

We have been a old customer of Eureka Forbes since 1990 and always loyal to this brand but we have been cheated by one of your sales person " Raju Rajak 09002414" when we planned to replaced the old water purifier against new ones dated 29.08.2020. Since we purchased the new machine Dr Aquaguard Nrich HD UV we have been going through night. The salesman mislead us with fake information and sold this faulty machine to us which is not at all compatible to our place and often broken down since every month we installed it, just to fulfilled own monthly target how someone trapped the customer that we have learnt from a big brand like yours.
We are now totally pissed off and planning to go legally and thought of complaining last time in hope of good resolution.
