Vizio Myles Bailey Faulty product, Swapped so I cant return to store , Internet

I contacted Vizio regarding a wifi issue on this tv model e552vle. I was unable to connect with wifi, but able to with a hard wire connection. The representative said they could come replace the tv as soon as I sent the receipt with the serial number and model number. I did that on 10/6 and was called confirming that she had received the copy, and would be setting up the swap for tv. I then received a call on 10/9 from the same representative saying i needed to send in the scan of the receipt before they could schedule a tv swap... I reminded her that she just called me a few days ago stating that she had the copy. I then had to scan and email the copy again, and my tv swap was pushed back. I received the new tv on 10/12, and they took the "damaged tv" with them.

This new tv would not connect with either wifi or hard wire connection. I called the customer service number and went through the trouble shooting once again. I then was told they would have to send out a technician. I refused and said i would like a refund for the product. I was denied a refund, and then spoke to a supervisor Myles Bailey. He did trouble shooting again, and i still cannot connect to apps and lose connection if ever i do connect. I asked for a refund and i was told i would have to wait for a box to be mailed, send in the tv, and wait for it to be inspected before getting my refund of the paid price and no sales tax would be refunded. I believe they purposely swapped the tv so that i couldnt return it
