Calcutta Electric Supply Corporation [CESC] — Incorrect / Inflated bililngs

This is regarding inflated billing for my electricity connection with Consumer No. [protected]. Please note my home is vacant & there is no electricity consumption since last 1.5 years. However, I see adhoc meter reading updated on my monthly billings & it is creating outstanding amount of Rs. 2, 070/-.
Looking into my past billing details, I see August 2019 bill reading as 2414 units which was paid in September 2019 (before due date). Since July 2019, I was out of my home & there is no consumption. However, recent billings for Jan’21 shows meter reading as 2723 units, whereas actuals meter reading shows 2414 units. As the home is vacate for more than 18-19 months there is no power consumption since July 2019.
Request your kind effort to align the billing & meter reading as per actuals consumption & highly oblige me. Appreciate & looking forward for quick action on my request to correct reading & send me fresh bill.
