Delhi Jal Board — MLOC average billing

I am user of water connection (K no. [[protected]]) at house no. E-16, First Floor Sector -1 new delhi.

Meter reader has not come to our premises & now we found a bill dated 15-July-2022 amounting to rs.468/- (For the period from 15-May-2022 to 15-July-2022 with service charge - consumption between 20-30 kl)

The consumption has been averaged and reading/meter status has been shown as Mloc (Meter locked). The status of reading is shocking to me as we have 2 persons always present in premises. they are not taking reading Since 23 NOV 2021 and continioulsy showing MLOC And Charged average every billing cycle

Please solve my issue
