My consumer number is [protected]. I have installed water meter from past few years. I am consuming very less water but i am getting high bills. Your officer does not take my water bill reading so how can bill generates. I live alone in my house. Some times i am in office and they came to my home for reading but my door closed as i am in the office. Kindly look into this and help me in this.
