Bangalore Water Supply & Sewerage Board [Bwssb] — high bill amount due to wrong meter reading captured by bwssb from past 1 year

Water meter shows 3704 however for the past 1 year, the water person has been mentioning the excessive amount. He has captured as "2703000" (Wrong reading) which is ridiculous. Water bill will come around rs.500 however because of this excessive reading, it shows we need to pay rs 9000 we have faced a lot of mental pressure because of this problem. We have not at all consumed so much of water. We never see the person coming to take meter reading to mention the exact meter readings. We need a person from the water board to visit our home and resolve this problem as soon as possible.
This is a serious issue and we need your assistance and involvement in solving this problem. Recently we were advised to lodge a complaint as our mental health is at stack!!
