Hunter Oil & Propane

We were advised that our debt was paid off. Therefore allowing us to change propane providers, which we have done so already.We initially had Hunter Propane as our propane provider. During our agreement, there were several discrepancies on both parties. After which we decided to go with another provider. During that transition, we were told that we needed to pay off our balance before the new provider could claim the propane tank as theirs and start supplying us with propane. Well, we paid off the balance and since then the new provider has been supplying us with propane now for approximately 5-7 months. Hunter propane is now claiming that we had an outstanding balance off $146.47. We should not have a outstanding balance or we wouldn't have been able to get a new provider. Propane companies have to buy the tank that is in the ground from the existing company in order to start supplying propane. Hunter would have not agreed to this if we had an outstanding balance. We wish for this balance to be taken by Hunter and our debt wiped away.Desired Settlementthat our balance be wiped away!
