Delhi Jal Board — Not providing correct bill

Address:

New Delhi, Delhi

Hi, I registered a complaint with Delhi Jal board and asked them to do the required correction in my water bill and provide me with correct bill so that I can make the payment of correct bill. However even after submitting a letter with all supported documents they havent taken any action against the same. I even registered a complaint with djb customer care and even visited their office many times. Still nothing has been done and it has been more than a month now. Can anyone please look into this and take corrective action against them. Thanks.
