Straight Talk Tracfone no refund Miami Florida

I bought the Straight talk kit because I am on a fixed income and I am trying to get my monthly bills as low as possible and my verizon Plan was too high so in order to lower my bill I went with Straight Talk. When trying to change my Verizon over to Straight Talk I find out that my iphone 6 plus was not compatible with their service. I was told to take it back to Wal-Mart where I bought it only to find out that they couldn't refund my money because the first agent tried to put my phone with a new number thru so the kit was usless to them. The 2nd agent I talked to told me to send it back to them and they would refund me my money after they recieved it. I have called a few more times but as of yet, nothing. Oh ya they informed me that they recieved the kit after I gave them the tracking number and it would be 30 days until I would recieve my refund, almost 2 mounths now.
