I had a propane tank that was "leased" from a local company. The lease consisted of if I used at least 700 gallons of propane a year there would be no charge to use the tank. With recent price drops it made sense to purchase my own tank, able to get the propane for approx 1/2 the price it would cost me to buy from the "lease" company, basically able to pay for the tank after a year or two. So get the new tank and tell the company to come get their tank they installed 8 years ago. Just received a bill from them for the materials they used to level the lease tank, the line to the house and a regulator along with a charge to pick up the tank. The charge to pick up the tank is spelled out on the original invoice, so I'm ok with that, but the other cost were just itemized on the original invoice with no cost. Can they really charge me for this 8 years latter, especially since a price wasn't listed on the original invoice? Attached are links to picture of a copy of the original invoice and the bill they sent me. Any advice?
