I would like to mention that till dec.2016 i recd. Bill of min. Charges as my flat was unoccupied since 2012. From the month of jan.2017 the bill shows the meter as faulty, units consumed 100 and bill amount rs 610 onwards.
I visited your office on 11.02.2017 and submitted photocopy to your staff for correction and paid the excess bill on 25.02.2017.
For the month of july 2017 i got bill for rs2230. I got it corrected from your office and paid the bill of rs.350 and again on 19.9.17 i paid the corrected bill of rs 450. For sept 2017 the bill amount was rs.60 and for oct 17 rs 530.
Meter is faulty then on what basis the units consumed is calculated.
Please replace the meter and charge me as per my consumption.
