Bangalore Water Supply & Sewerage Board [Bwssb] — Water bill is 1300

Dear Sir/Madam,

This month we have got the water bill around 1300
Compared to previous one year it is 1000 more,
We usually get the bill around 300-400.
And the usage/consumption of water in this month is still same.

Could you please check this if anything has gone wrong.
Here are the details:

Bill Period: March

Thanks and regards,
