Thrift Propane Thrifty Propane took my money, but three months later, still have not delivered the tank Medina Ohio

On October 21st of 2015, I called Thrifty Propane to inquire about purchasing a propane tank.  I left a message, within a few hours, Scott from extention 797 returned my call.  He was very rude, but answered my questions and I paid almost $800, using my debt card for a new 120 gallon tank to be installed at my house.  I called him back almost a week later to set up the delivery of the tank, he was again rude, telling me that is not his job but he did finally give me an extension to call to set up the delivery.  That extention was 715.   I have called this number more than 20 times to set up the delivery.  I have never once recieved a return call.   I started "live chatting" with the company in December explaining what I have been through.  They said they would forward my information to the correct people.  Again after more that six chats, no response.   On December 30th, someone did call.  She said she was not in the office that sets up deliveries, but could offer me a used tank to be installed on January 14th.   I was not happy with the tank or date, she said to call extension 723.   I have not called that number repeatly, leaving a message each time.  

I do not beleive I will ever get a call back from this company and have requested a refund.  Of course the only way to make this request, since I can never get anyone on the phone, was to do this over the live chat.   Since this method of communication did not get me anywhere before, I doubt I will recieve a refund this way either.
