We booked our Hertz car rental in France via AAA and there was an unexpected change: our cross-channel ferry was canceled so we had to rush to a different French ferry port. As soon as we were notified (by text message from the ferry company), I quickly called the main Hertz number to tell them that we needed to drop off the car in Cherbourg instead of Caen.
The Hertz agent said "Oh, you need to call AAA because you booked the rental through them." This was insane because I was calling at noon in France, and nobody would be in the AAA office where we booked the rental until a few hours later, when we'd already be on the boat.
Lacking other options, we drove to Cherbourg and dropped off the car in the ferry terminal parking lot, using the deposit box to turn in the keys and contract. But ... what if we'd had an actual emergency where we absolutely had to talk to someone? AAA would not have been able to help us, right? I am curious whether anyone else has experienced this problem when booking through a middleman like AAA instead of the actual car rental company.
