Calcutta Electric Supply Corporation [CESC] — Excessive Electricity Bill - Customer ID - [protected]

I have received electricity bill of RS. 4100/- on 13th Feb 2022. Please check why so much high bill is created. Please regenerate bill with proper amount . This much high bill for a domestic client is not acceptable . We are a family of 2 people with minimal appliances in my home . We also don't have AC in my home .
