I am reading all the complaints, and our situation is the same. They keep filling tanks as soon as prices go up and there never seems to be a supervisor available to answer questions. We have 4 tanks, and we were suppose to be locked in at a price, and they never do. I understand you own the tank, after you have had it for atleast five years. Please help me get out of this situation. I would like to use another gas company, but they said I cannot, because they own the own. Any advice would be appreciate.
