[Resolved]  Delhi Jal Board — Bill sent including arrears though no arrears are due since last four bills.

I have already paid all arrears and all dues time to time and due to the mistake in preparing the bill I have to personly visit to the Office of the Jal Board( which is far from my residence) then only I could make payments.
It is also informed that payments of bills as stated above are made on time and a written complaint was also sent to the Office of the Delhi Jal Board, Office at Yojna Vihar, Delhi-92 which was duly received by the concerned clerk and an endosement no. 139 was made over the copy of the complaint.
The details of my bills are as under:
