Bangalore Water Supply & Sewerage Board [Bwssb] — No proper water

The complaint is all about no proper water supply from the responsible person.We are allowed to get water weekly once just 2 hrs, which is not at all sufficient. My parents are aged they cannot come directly to office for registering complaints.If they ask that person. He is behaving without respect.We are buying water tanks every week which is again a burden to us financially. We are paying our water bills regularly but still the water scarcity is really high.
