Delhi Jal Board — Complaint About Excessive Billing K.No. [protected]

Dear sir,
I am writing this letter to request you to look into the water bill for K.No. [protected] (bill name: Shri. M.P garg. We received a water bill of Rs. 22018 for the duration of the last 4 months (120 days) on 11/11/2021. My average water consumption in a family of only three people was only 5-10 units per month from march 2021- june 2021 our bill was Rs360.
We did not increase our consumption and some errors must have been made during the calculation of the bill. Therefore, I request you to look into the issue and send me the updated bill.
