I have moved into my current address on December 20 last year and have never used gas in the past five months. Why do I keep getting billed? I didn't pay much attention to the first two bills, thinking they were account opening fees, so I paid them. When the third bill came, I found that the gas meter was off and the number had not changed since I checked in. What is this bill based on?I hope the relevant person can give an explanation.ThanksDiamond
