Calcutta Electric Supply Corporation [CESC] — excessive electricity bill amount

Address:

Kolkata, West Bengal, 700032

Dear Sir,
This is to inform you that, I Mr. Devjyoti Mondal, Customer ID : [protected], Consumer No. [protected] received Electric Bill on 28.12.2017 and my Bill amount is very high Rs. 3980/-. This Meter only use for domestic purpose and my last months (16/11/2017) Meter Reading was 921. After your bill received I also checked my Meter and Unit shows 947 (30/12/2017) but my Bill shows Total Unit used - 1382 which is absurd. This meter only using for AC purpose.
So, I request to you kindly look in to this matter in regards to excessive Bill amount which is very big burden for me and resolve the matter as soon as possible so that I will be ever grateful to you.
Thanking You
Devjyoti Mondal
