Calcutta Electric Supply Corporation [CESC] — Exorbitant amount of bill for the month of June,2020

I, smt. Purnima mukherjee having customer id : [protected] and consumer no.: [protected], would like to state you that i have received electricity bill for the month of june, 2020 amounting to rs.5560/- only. The payment due date of the same is 27/07/2020. Now, it has put me in great anxiety as to how i could manage to pay such a huge amount being a family pension holder getting a meagre amount of pension per month.in this context, i'd also like to state that i have already paid bills for the months of april and may, 2020 amounting to rs.3, 370/- and rs.1, 540/- only respectively within due date. You have stated in the bill for the month of june, 2020 that overall consumption is higher which could have been due to increased usage during lockdown and it is shown that unit consumed is 607, but it appears to be incorrect as i have not installed any kind of additional electrical appliances during the last 5 years which could have made such an increase in consumption. Any inspection in this context is appreciated from your end if you wish.
In view of above, i request you to consider my case and do the needful in this regard.
