Bangalore Water Supply & Sewerage Board [Bwssb] — Overpayment of water bill

Address: 303, Mythri Maiden Apartments, Somasundarapalya, Bangalore - 560068

My society is charging me 6521 for water bill for the month of July, Aug and September which I feel is too high and almost double to what I am paying as electricity bill. And considering winters in Bangalore we use very minimal water at home. This bill is generated by my apartment Mythri Maiden Apartments. And they didn't even share a proper bill. I feel something is not right and hence, lodging a complaint here.
