Hi, We are presently shifted at Delhi from March 20th onwards. Already paid the bill till March 2019. Received advance bill payment notification for Apr-June 2019. Which is very high. We will not come till November 2019.
Kindly advise and solve the problem.

As per electricity bill of for the month of APR, 2019-JUN, 2019 against
Consumer Id :[protected] the total due amount is 2357/-INR. But as per the last due bills where we used electricity and staying at home that was 1852/-.
Kindly justify this issue. In other electricity board we never received any advance bills.
