I'm not satisfied

I called ACO from the Airport just after 12:00pm to send a shuttle car. My pick up time for the car was 12:00pm. By the time the shuttle picked me up and brought me to the location it was almost 2pm. They then hit me with a bunch of hidden costs and my total cost went from less than $100, as was expected, to $350 in the end. They said that since I wasn't there at 12:00pm to pick up the car, they couldn't hold it for me and they had to upgrade me to another car which cost $90 more. I called them just after 12:00pm to come pick me up and this still happened.

There should be more visible information on such things that they might give your car away if you're not exactly on time. They should be more detailed that if you don't buy the third party insurance, they will not give you the rental.
