Telangana Southern Power Distribution Company [TSSPDCL] — I am complaining about the wrong electricity bill

I am a new resident to my present house. It has been only 11 months since we shifted. As there is lockdown due to covid19 electricity bill collector is not allowed to check the reading so govt has declared to pay the bill of last year's same month i. E., may month bill. But in the last year construction is itself not completed and as a result service number is not allotted. But still we got a current bill high. So i request you to reduce the bill for which we didn't consume.
