Igl is sending my wrong bill everytime as they have entered wrong meter number in the data
I have told them many time but no response
Every time they came and took the meter photo but never generate my bill accordingly and say that u have not allowed the person to take the photo.
Now when i have stop doing payment they have disconnected my connection
I want my bill to come according to the meter reading not on the random basis
Kindly take the immediate action toward this matter
