Bangalore Water Supply & Sewerage Board [Bwssb] — Water supply irregular and low pressure

I stay at Maruthi nagar, 4th Main, 3rd cross. In our area, water supply is supposed to be on sundays and thursdays, but since past many days, water supply in our area is irregular, having very low pressure, hence water quantity is inadequate and we are forced to pay high amount and buy from outside. the engineer and valveman avoid phone calls or do not respond properly. please look into this and ensure proper supply of water.
