South Bihar Power Distribution Company [SBPDCL] — Rectification of erroneous bill

Address: Kankarbagh Patna Bihar

I had taken electricity connection in jun 2017 for completion of construction work in my new house. Since then, i used to regularly pay my bill ranging from rs 400 to rs 800 per month which was accrued due to the construction work as no one stayed there. After lockdown, construction work stopped. On 11th june, i paid a bill of rs 421 for the month of may. Till then things were fine.in july 2020, i received a bill for rs 17000 approx and for august, rs 10500 approx which was very abnormal. I request you to rectify my bill and do an average of my past bills as it is really unfair for me to be paying this when not even a single person is residing there and the house is still vacant.
