Mahadiscom — Wrong & high Electricity bill charged when Meter is not in use for Nov-2014

This is Suresh, and this email is regarding wrong electricity bill charged for me. Since last 6 months i am out of the city and i have paid the advance amount and only nominal charges are expected for each month (fixed charges of Rs: 40). Its been working fine till last month, now i see for Nov - 2014, MAHADISCOM has charged 180 units which comes to Rs: 1032 payable by Dec 5th. (Rs: 1032 less advance available in account Rs 340+ = Net Due : Rs: 690). Please check the Meter reading Current & previous is same "3909".Please clear the confusion, or let me know the concerned authority to whom i need to take this forward.
