Bangalore Water Supply & Sewerage Board [Bwssb] — exorbitant bills

I have been handed over BWSSB bill of RS.10, 491/- with a consumption of 2, 14, 000 litres. we are a small family of 4 people staying i the same house paying monthly bill of Rs 300/- to Rs 400/- only. The BWSSB has resorted to hike up the bills unethically to loot from the public during the tough covid times.
