Tamil Nadu Electricity Board [TNEB] — EB Amount Charged Twice

I am currently residing at 192, S.NO 113 / 1A1, THATTAKULAM ROAD KOLAPAKKAM, CHENNAI, which is having an electricity connection bearing consumer number [protected], Divisional Office 261-Nandambakkam. Today, I was shocked to receive the current electricity bill for an amount of Rs. 5124/-. My monthly electricity bill amounts generally range between Rs. 500/- to Rs. 2500/- The bill for this month July is almost twice the amount of my regular bills I investigated the matter from my side to find out the error and I noticed that the previous month I charges as PMC mode. If you charged like this as consumer I have to pay more amounts. As you will notice, there is clearly an error in it. I, therefore, kindly request you to correct the current bill and issue a fresh bill for the current month. I hope my complaint will be resolved as soon as possible.
