Delhi Jal Board — wrong inflated bill kno: [protected]- bill no[protected]

Address:

New Delhi, Delhi

I am resident of wz-75 groud floor, we are 2 in family and never consumes more than 20 unit.
I received bill of 2000 rs and meter reading shows mloc. However meter is place outside of house along with other resident's meter. Other floor residents of my building never faces this type of issue.

I had same issue last year and replace meter and get it rectified by visiting jal board office but this is happening again.

Please resolve
