Calcutta Electric Supply Corporation [CESC] — unexpected bill on may 2020

Dear sir,
The current bill i received from cesc is unbelievable. It shows a consumption of 449 units. Never in my history of consumption history, have i seen such a high bill. There was no one who came for taking meter reading since lockdown 1. The bills generated were assumed values. This current bill for may 2020 shows an unbelievable amount of rs. 3220. Also i have stayed this home as rented. My customer id. : [protected] name of the bill ajit das
