Have reservation but Hertz has no car
I arrived at SJO (Costa Rica) one hour after my reservation start to be greeted with " sorry we have no more cars". I was handed over to a representative of a local car rental company, shuttled to their location and given a very beat up car, of same class as reserved at Hertz and at the same price. In the end all worked reasonably well with that company, but this is absolutely not what I expect from Hertz.
What can I expect from Hertz, where should I complain?
Needless to say I didn't get the points .
