I needed to change drivers on the rental to pick it up but the rental place said Hopper had to make the change and Hopper said the rental had to make the change. I would have had to spend a few extra hundred bucks to get a car and ended up losing the money I paid and not being able to pick up the car. If I'd just rented through a car rental agency directly none of that would have been a problem. They did end up giving me a refund for the car I was unable to pick up, so 1 more star for that.
