Tata Swach — Inefficient customer care

I bought Tata Swatch Smart from a very renowned place in Bangalore. After using it for less than 2 months filter the stop filtering the water. I called the helpline number and ask them to send some technicians. I lodged that complaint on 6th of April 2015. Now today in 28th April, even after this 22 days no body contact me for this complain. Instead everyday I called the customer care no. and they said we will shortly do that. Whenever I asked for senior member in the call they said they are not available and if available they keep me waiting on the phone for more than 10 minutes to respond. Is this the way to handle a customer under a brand like Tata?????????? Now I don't want any technicians but send somebody to my house to collect your garbage product. Money is not everything but who will be responsible if i fell sick due to drinkng unhygenic water?
