Priceline.com Priceline, Fox car rental False advertisement, refusal to correct the problem. norwalk conneticut

On July 9th, I used the Priceline.com app to find a car rental in Miami, FL.  Knowing Priceline guarantees lowest prices, I felt I would have no issues finding the lowest price in the area.  The displayed some choices, of which I chose Fox Car rental, which happens to be outside the airport and one needs to get out, take a shuttle to get to their building (I am guessing is the reason for their lower prices). 

I chose an economy car, and with insurance and taxes, the total came to about 38.  I was happy with it.  I felt it was booked, done and my car would be waiting for me.  I found out to my dismay once I took the shuttle all the way to the airport that they claimed my "economy" vehicle was not available.  As a result they would have to upgrad me to a standard vehicle.  They charged me extra for the upgrade when I felt they should not have charged me since this was their problem not mine. 

Their upgrade was to a small Toyotal Corola which I do not consider "standard size sedan" it is pretty small.  They also informed me that although I had paid extra on the priceline app for insurance that it did not really cover my car and they had me jump through hoops, showing them documents of my own insurnace or they would not let me take the car out.  They had me sign all kinds of liability papers, making the whole experience very awkward. 

I was quite upset that my price jumped up over 50 dollars and that my insurance I paid for was not really covering me.  This to me is a perfect form of false advertisement and lack of quality control between priceline.com and the companies it uses. I am very dissatisfied and feel this is unacceptable.  What is more, when I tried their customer care on their website, there is NO way to find an actual live number, and on their chat program, the person supposedly doing the chat support with me blew me off, saying they have no policy to give me a refund or credit.

  They said they may email me with a coupon toward my future purchase as if I would ever use them again.  I am posting on all my social media letting them know NOT to use priceline.com and certainly not use fox rental services.
