Tamil Nadu Electricity Board [TNEB] — Huge bill amount

I have received huge bill amount for this month Rs4284 and I usually get 1000+ for a bill and I have paid 170rs for last bill and didn't informed any further update but they put two month bill and doubled it and it is not my mistake. I am paying the bill in time without any delay.

Please revise the bill as usual and do the needful.
