Bangalore Water Supply & Sewerage Board [Bwssb] — I am complaining about the excess amount in bill with RR NO S-453227 and bill dated 12/02/2022

Dear sir/madam,
With reference to the above, last month and this month I have been recieving a bill amount of RS 900 even though I am the only one staying in this whole building. The ground floor house has been vacant for the last four months.
Kindly look into the issue and reduce the amount.
Thank you.
