Telangana Southern Power Distribution Company [TSSPDCL] — Overbilling of electricity charges

My USC no. Is 09859386 have been billed for an amt. Of Rs.2964 for the month of Sept'2021 on 12.10.2021 without reading the meter since our door was locked. When enquired, it was informed that it will be adjusted in the next month bill and hence payment was done.
In the month of november, meter reading was done and units charged were 267 and an amt. Of rs.1077 was deducted from rs.2964/- ( sept.' 2021 bill amt) and bill was given as rs.(-)1885/-. I was expecting the same will be taken care in the next bill, but to my surprise, bill generated in the month of December 2021 was given as rs.184/- for 72 units without adjusting from the overpaid amt of rs.1885/- and the same was also paid by me along with all my personal bills online.
Hence it is requested to kindly arrange for refunding the overpaid amt. Of rs.1885/- or adjust the amount in the upcoming Bills.
