Torrent Power — Complaint about bill calculation for the month of June 2020

We (Service No - [protected]) have received an electricity bill in the month of June 2020 after 4 months (March, April, May & June) claimed total used units 796 which is charged by 8510 rs. I would request kindly share a detail calculation for the charged amount on used units.

Also, there are some mistakes/discrepancies into claimed units on the App bill & Ebill /hardcopy bill for the month of February, March, June & July 2020 which I am attaching below for your reference.

I already visited a local torrent office but did not get satisfying answers or calculations from the customer care executive.

I am the only bread earner after my husband passed away. This is the huge amount to paid.

Kindly do the needful.
