Consumer Redressal

Hello! I am Pinaki Chatterjee writing regarding a big surge in my residential current month CESC electricity bill for June 2020. I am a service professional working outstation in Mumbai and currently located in Kolkata due to a sudden fatal fire accident and subsequent demise of my mother, the late Mrs Supta Chatterjee 3 months ago, I am currently stranded in Kolkata due to the ongong Covid 19 lockdown here. The current house is our family residence in North Kolkata and my deceased mother use to stay here alone since my father's expiry 8 years ago. The house belonged to her and also the electricity bill use to always come in her name. The average bill that normally would come is always below 1000 rupees and the unit consumed are usually below 150 as there are no AC's in the house or any other major electric consuming devices and I am staying here all alone in the house. Unprecendently, this month I found out online that the electricity bill has jumped up to more than double and the current payable amount send to me by CESC is 2810 and the units consumed is jumped drastically to 385. I find this bill absolutely incongrous and bizarre and the last date given to pay this bill is 27 June 2020. Please guide me as to how to go about taking immediate corrective measure and necessary action against CESC for sending me such an unscrupulous bill and rectify this erroneous bill asap. Look forward to your prompt response. Thanks/Regards, Pinaki Chatterjee
