Delhi Jal Board — about bill

Address:

New Delhi, Delhi

My k. No is [protected] in the name of sunita bansal, r/o a-393, sarita vihar, new delhi-76. My issue is that i m not receiving water bill from last two years n on continuous complaint to the meter reading boy i always get the answer that ur bill is going in minus as now water bills r reduced by mr. Arvind kejriwal but yesterday when i went to nearby djb office they gave me a bill of rs.20, 000/-. Now what can be done as we can't afford to pay 20, 000/- in one go.
Kindly take some action n give us a waver as mistake was done by ur end.
