Bangalore Water Supply & Sewerage Board [Bwssb] — incorrect meter charges reading

Address: 560086

We have been charged excess than the usage as the meter reading is not correct and need a service/change in the meter, kindly arrange a visit to the residence to resolve at the earliest as we have faced huge loss with the bill. We are also not notified about the readings in real by the meter reading person every month, there is no proof for the same.
Kindly help resolve the issue asap
