Rustomjee — no filter provided in ro filter by the builder

Address:

Mumbai City, Maharashtra, 400051

The filter of ro provided by builder (Part of the contract) has been provided without a filter. Further we had moved in in july and 1 year warranty was to be provided, the same has not been given.
There was no indication till 3 months that machine has issues. The indicator (For filter change) has come only at the end of 4th month.
This is reckless and irresponsible behavior on our their part.
