Calcutta Electric Supply Corporation [CESC] — Billing issue

This is for your kind information that I have received the bill for the month of March, 2022 is amounting to RS. 1940. though my house was closed for that month for approx 25 days then how could such huge consumption of electricity can be made in just 6 days of the month.
the Six month consumption are :
oct - 226 units
nov - 190 units
dec - 92 units
jan - 97 units
Feb - 67 units
march - 273 units

We are the family of 2 members can you just calculate and give me details that how could such huge consumption done in just 6 days of a month.
