Suburban Propane

We have a gas fireplace and fill it once a year. We called the local Suburban Propane to ask for size of our tank and pricing. We were quoted 4.63 a gallon. They said we had a small tank, we did the math and told them to put 50 gallons in. That Monday the bill was at the door and they filled the tank up and charged us for 81.3 gallons making the bill $386.00 and filling it more than we ask them for. I had a neighbor down the street and called him to see which propane service he used. He told me he just filled his tank and they charged him 2.45 a gallon (a different supplier). I researched the current pricing and found the US Government propane prices for the Northwest zone and the current residential pricing was 1.99 per gallon. I called the local Suburban Propane office and complained and they told me to tear up the bill and they would send me a new one and charge me 2.65 a gallon! That reduced the bill to $225.80. The reduced bill never showed so after 30 days I called again and she promised it would get taken care of. They told me to pay the $225.80 against the 386.00 and it would be taken care of. I sad no way would I pay the bill until they reduced it to the proper amount. The made the change several days later and i paid the bill. What a ripoff to the consumer and people who let them charge what ever they think they can. This is a large publicly owned company and that behavior should not be tolerated.
