Consumer Redressal

I am a retired Assistant Post Master General residing at the above address. My compliant is against the Electricity Board staff at Melur Branch, Minjur. My SC No. is 025-0080266, Meter No. 10076635. Nobody came to note the meter readings, but i took the reading on 20/4/12 and went to their office to pay the bill. The lady at the counter speaking over her mobile, carelessly entered 11870 units instead of 11570 backdated as 9/4/12. When i noted that she had made a mistake, she said it cant be altered and i have to pay for the unused units also. I was running from pillar to post to get this corrected for no fault of mine for the past one week from AE to JE and to all available staff.Nobody gave a proper response. Since the due date has come, when i went for payment, they charged me a late fee of Rs. 70/-. They get salary shamelessly for this kind of a poor work and we consumers suffer a lot due to such EB staff. Kindly take the required action soonest possible and provide me the remedy.
