Bangalore Water Supply & Sewerage Board [Bwssb] — Unusually inflated bill

Address:

BWSSB, Bangalore South

I pay the water bills for our apartment. Usually, it comes to Rs 6500 approx. However, this month, it has come nearly double, i.e. Rs 13, 332. I checked and found that it was not due to excess water consumption. FOr some reason, they have charged Rs 5214 for "LESS CONS 79000 ITS PM FROM APR 21 to AUG 21". Also, under the present reading, it says "Things Collect".

The bill has never come like this. Kindly clarify these points. I have attached the bill for reference.
