Absolute terrible experience with this dealership....

Absolute terrible experience with this dealership. I bought the Car Doc service plan they offer which includes a rental car when you bring your vehicle in for a service. I had a 2012 Ford Fiesta, so I was frequently bringing in the car before Ford bought it back from me under the Lemon Law (not their fault Ford made a terrible car), and had several issues with the services they provided on my car.
First, their service team incorrectly installed an oil filter which caused almost all of the oil to drain out of my car.
Another bad service came after one of the times I had work done on my transmission when a week later the check engine light came on. Turns out one of the vacuum hoses for my brakes came loose, I'm guessing the technician forgot to put the clamp back on, thanks guys.
Back to the rental car. The first few times I took my car in they called Enterprise and had them pick me and gave me a rental car. After those first few times I brought my car in for a service and was told I no longer had the rental service. When I bought the service plan I was told that I would have that rental service for the life of the Car Doc service plan. They ended up giving me one of their loaner vehicles, but I had to fight for one every time I brought my car in, for a service I PAID for.
Lastly, when I was going through the buyback with Ford their employee handling my case told me I would be receiving a full refund on the service plan. I thought I had read that I would receive the amount for the services I had not used, but she assured me Ford would send a check to make up the difference. Turns out I was right, just another example of the incompetence of the employees at Harrold Ford.
