Delhi Jal Board — high bill rate without checking the meter unit

Address:

A-235, street no.9 madhu vihar, New Delhi, Delhi, 110059

Dear team, we have delhi jal board connection along with the meter to check the unit.

Last month we noticed that no employee from delhi jab board came to check the notice and trach the record and after the month we receive a bill of rupees 1200. I want to know how they to any consumer and they generate bills for the consumer without taking a reading from the meter.
