Delhi Jal Board — Wrong reading captured by reader

DJB reader generate bill without visiting the place with any random number. When we call reader he ask not to pay bill and he will correct in next round. However, we got penalized for late payment charges and the bill never corrected. Now they made mistake with intentions and we need to rotate around the DJB kakrola more office.
From last 6 years I have been through the situation multiple times. And your self reading is just a joke never work.
