Calcutta Electric Supply Corporation [CESC] — High Electric Bill after the installation of a new meter

Address: CESC Limited CESC House Chowringhee Square Kolkata – 700001

Since last 3-4 months I am receiving very high electricity bill from CESC Kolkata. This has stated happening after the old meter was replaced by the new one on May/June 2021.
We had put up a request to upgrade the load capacity as we planned to install another AC. Accordingly new meter was installed. But, despite running the second AC on rarest of the occasions, it is found the bill amount got doubled (average 3, 300) compared to the amount we used to pay (Average 1,[protected] when we had old meter

I have a doubt in my mind that the new electric Meter is not working properly because the rise in bill started happening after the installation of a new meter.

So request you to kindly look into it & resolve it as soon as possible.
