Consumer Redressal

My consumer number is 3222 0303 743 with consumer name Srikanta Chandra Das. In December 2019, I received the electricity bill as Rs.4376= which includes the current month bill as Rs.1641= and arrear amount as Rs.2785/= which seems to me an erroneous bill and I request to correct the bill. Here the summary of the bill of different months: Dec 2019--- Bill amt: Rs. 1641/- Jan 2020 --- Bill amt. Rs. 367/- Feb 2020 --- Bill amt Rs. 487/- Mar 2020 --- Bill amt Rs. 487/- Apr 2020 --- Bill amt Rs. -170/- Looking at the trend of my electric consumption bill, how the Dec-2019 bill can be this huge amount like Rs. 4376/-. I request to urgently rectify my bill amount and send me the correct bill. I have paid so far all the bill amount except the arrear amount which seems to me the erroneous amount.
