Level of TDS in water purified by Eureka Forbes aquaguard

The product delivered is showing TDS of 150 which is not drinkable. The technician did not fit the new product well and I am still buying water from outside. Complaint was registered the same day it was fitted. ticket number is CM-14xxxx5-5xxxxxx4. No one from the Company has still attended it. I am still buying water from outside and no one is picking the calls. I tried reaching to the sales team as well the customer care numbers. I am facing trauma and insecurity about the amount paid and buying water from outside.

I logged a complaint with them and they say the case is closed I have still the ticket open where I raised the taste issue same day filter was fit. I still have the app complaint open. They said they have open a sales complaint cm-1xxxxxx5-5xxxxxxx9 for refund or replace but that too has not happened. When I wrote the same to grievance officer got a response that resolution is provided.
