Since when do reservations mean nothing?

Hertz over booked. There were three of us there for one pickup truck. Needless to say, I didn’t get that truck. The one that arrived late got it because they called to make sure it was there. Thought that was what a reservation is for. Didn’t get a truck until two hours later. Missed a deadline and will have to rent another truck to finish my project at a later time. Was not happy with the experience. It is definitely going to cost me a bit of money.

Process of reserving was easy, but see comments above
