So I got a letter from our natural gas supplier yesterday..it went on to explain that my gas consumption is less than half of what I used last December, it went on to say they are going to send out an inspector and inspect the meter. If they noticed any tampering of the meter I could be in serious trouble. They recommended that I call customer service to set up the time for the inspector to visit my home.........SO I called the nasty lady at national fuel and explained that I was now using my fireplace insert more frequently and that I had turned my thermostat to less than 65 degrees. She put me on hold for a while then returned....She ran it by her supervisor and said there is no way a fireplace insert can reduce my gas consumption by that much...I explained that my insert is highly efficient and produces a large amount of heat and on and on and on....she put me on hold again....after a half hour on the phone they are still sending someone out to inspect the meter....I told the wench to also check out my wood pile in the back yard and then hung up on her!!
