Address:

414302

Today15 oct 2017 i received sms from msedcl
The meter reading noted by the man is 910 on 14 oct 2017 at 16:55.
Therefore i checked meter reading taday at 21:15. I see a meter reading is 902 only.
What is this?
The man appointed for taking meter reading is careless. Why the consumer pay large bills. At our home we have 1cfl, 1 zero bulb (Lightening at night only) and one 60 watt bulb.
Apart from this one mobile charging is there. We get bill of month for the unit more than 40 units.
Most of the time my father complaint moraly to the office and the he get reduced bill. But it happens repeatadly
Help me
