Hello Sir/ madam,

Refer bill no's - n[protected] / 020/ 030
From past 2 months suddenly my bills have increased to more than double. The amount was always below 500 or 750.
Since 2022 january the rates have doubled.
Where as we hardly use water as it is a office space with max 2 occupancy.
Consumption - Toilet or washing hands, watering plants.
Non consumtion - washing vessels, bathing etc

My friends place they are a family of 4 and their bill is coming only 650.

Hence i am being charged SC charge for borewell of Rs. 500/-
Please clarify as my bill is due and since 3 months i have been paying the borewell charges.
