AmeriGas Propane review: Price lock and delivery

I signed up for a price lock in July at $1.99/gallon. I gave them my money and thought all was fine until I ordered in September. Following that delivery, they told me that my price lock was still pending and I would need to pay market price. We were finally able to find some sort of resolution as they offered me the $1.99/gallon price for that delivery with a price lock offer of $2.55/gallon lock for future deliveries through May 31, 2024. However, I just placed another full order and they are charging me $2.88/gallon (market price). In addition, it has been over a week since I ordered the refill (which was promised by 12/18, and it has not arrived yet. As a result, my tank will be below 20% and I fear they will require me to have a pressure test. I am unable to speak with anyone who can help me. They either hang up, “lose” my call, or pass me around until I can’t take it any longer. It is well into winter and they have me over a barrel. I can’t go anywhere else and get a lock at this point, and even if I changed companies, I need tge tank changed out and the ground is frozen until spring. Please help!
