Mahadiscom / Mseb / Msedcl — very high bill in june 2020 month

Address:

Thane

Our average consumption of power is around 400+ units while in the month of june we were charged for 1841 units which is 4+ times more. I am aware many have complained about the same.
We are aware company officials could not come to take meter reading but somewhere someone in msedcl do not know how to take average.
Is there a remedy to this?
We should get a revised bill to be paid.
