One more error found
In current bill last month's units used is show (1213) whereas last month's charges/bill was charged for (1536) units.

I have highlighted all errors.

Should check to see details.
This amount of bill for 849 units used is not feasible.

Either this is clerical error or planted loot/plunder in my account.

Bill amount is not at all genuine as of our usage.
