Delhi Jal Board — excessive bill received on estimate basis for k. no. [protected]

Address:

New Delhi, Delhi, 110085

We have been receiving bills for the past two billing cycles (Bill no.[protected] &[protected] on an estimated basis without any metre reading. So far we have paid rs.7, 381.95 under extreme mental and financial stress and a bill of rs. 2754.58 is outstanding as on date despite no usage of water to this extreme extent.
When we enquired about the last reading in order to get our current bills revised it was reported as 887 units in contradiction with our current metre reading of 627 units
On more enquiry, we have come to know that the metre reading pertains to another water metre (Of tron brand) instead of our own water metre (Of kranti brand).
We had submitted a complaint in this regard on 26.03.2019 but so far we have not received any sort of response from delhi jal board.
This matter has imposed upon us an extra financial burden for no good reason. Kindly redress our complaint at the earliest so that we don't have to pay such heavy bill amounts in future despite of no usage of water to this extent.
