Bangalore Water Supply & Sewerage Board [Bwssb] — Water bill amount too high

Hello, i am resident of vidyapeetha main road banashankari 3rd stage, bangalore. From more than past 10 months, i have been receiving monthly water bill of more than 1800₹ even when i am not using that much of water. My RR no is: s-178202. I waited this long thinking that it might get fixed next month and so on but i recieved a bill of 2448₹ for the month of july which is totally non-justifiable. I request the authorities take note of this complaint and do the needful.
Regards,
A N Jayaram Murthy
