Delhi Jal Board — Wrong bill amount and wrong units

On my K.No. [protected] i receive message of bill amount for 27, 955.00 for 18 days of 472 units. I am still shocked how is it possible to get this bill amount. and i have register a Grievance Complaint and there is no resolution yet.

Today 24/02/2022 i receive message from DJB asking to pay the bill amount of 27KL 30, 183.00 Rupees for Feb month. There is no escalation matrix from where i can reach out to Delhi Jal board executive and to correct my bill.
