[Resolved]  Calcutta Electric Supply Corporation [CESC] — South City Kolkata wrong bill

Since last month I am receiving very high electricity bill from CESC Kolkata.Last Month Electic bills was 3546 Units, which is very much high than what it should be.
I have a doubt in my mind that either Electric Metre is not working properly or someone is doing Electric theft from our metre as we are unable to check what exactly happening because the metres are locked in a room.
So request you to kindly look into it & resolve it as soon as possible
