South Bihar Power Distribution Company [SBPDCL] — Wrong bill related

Address: Flat number 50903, Nikoo Homes 1, Bhartiya City, Bangalore.

High Meter bill. The house is closed from long time and we were paying electricity bill every month. The electricity bill for previous months was less but suddenly this month it came as Rs. 19485 which is not correct. Please support.
Also If I try to add complaint from sbpcl website it says wrong CA number. https://sbpdcl.co.in/(S(2haq50puzedcqagvolrild5p))/frmhome.aspx
