Tamil Nadu Electricity Board [TNEB] — Excess billing Of amt Rs 1040

Dear Sir/Madam,
This is Subramanian, I used to stay in Ambal Nagar, Pallikaranai. But now i have not stayed in the flat for more than a year, as i am in outside of town. But June month bill shows very high as Rs 1040. Also last 6 months bill cycle was Rs 0 except this month, If they asked to pay the bill of previous month it will be Rs 0 only. But not sure why they put Rs.1040 and it is not been used as much as this unit its unoccupied in the flat.
So please check this issue and revert the bill as we did not stay in the flat.
