Very poor / incompetent customer service (800 number, but was in LAS). Wanted to pickup wife's car since her flight was delayed by 2hrs and I was on reservation. First agent told me I'd have to cancel her reservation and make new one (at higher price) and got very rude with me when I asked her to get a manager on the phone. Then, manager says it will be no problem, but then proceeds to start to cancel reservation and make new one (which will be at full rate)... Had to stop her before doing damage. What's really crazy, is that she was going to cancel my wife's reservation (who has a different last name than I do, they had the wrong phone number for, and had no other proof that I even knew her other than I knew her name (I have no reservation number, wasn't even sure she was renting at Hertz. I told her that I was shocked she was going to let me cancel the reservation... She tried to defend it as not a bad idea... Indefensible.
I'm going to be writing another review about the last experience I had with Hertz too. It's clearly a very screwed up agency in the customer service department. She took my number, I know I'll never hear from anyone as was case last time. Don't rent from Hertz, they don't have a clue.
