With all the talk on here about propane lately, thought I would get your guys opinions. I live in northern Illinois, and just had my house propane tank filled. Driver says I used 50% more propane than last month, does this not sound right to anyone?? I was not home for most of the month and t-stat was set at 60, just like in December. Driver also wrote down wrong percentages from what the gauge actually read, different in starting by 8% and ending at 75 but charging me for the whole thing. Amount of gallons matches HIS gauge readings, not actual. Has anyone else had problems like this? Thanks
