I used to tell my friends in NY to take Hertz 24/7 to go to the airport and even possibly the FlyerTalk community. I've been dealing with Hertz 24/7 for the past week about a one-way reservation I had to LGA. This experience would be a cautionary tale for anyone planning to use 24/7 to go to or from JFK, LGA, or EWR.

The background of this is that I reserved a one-way rental in August 2013 for Saturday, September 7, 2013 at 9:00 AM for a one-way rental to LaGuardia. My wife and I were flying to Korea on DL via DTW. At any rate, they sent me an email at 8:31 AM, when I was already en route to the reservation site, that there was a problem with my reservation. Apparently the email also stated that they'd find me an alternative vehicle but there was no follow up to this at all.

At 8:50, I arrived on site at E. 13th St. and Fourth Avenue in Manhattan. Parking attendants said there was no car for me. I call Hertz 24/7 and a customer rep is looking for a car. She can't find any. By 9:20, she offered me to reimburse me a cab ride but I didn't want to have to deal with that. She then directed me to a normal Hertz location on Lafayette to get a one-way rental.

The rep told me that I would have to pay for gas but that the car itself would be free of charge. I was annoyed that I'd have to pay for gas since gas is normally included with a Hertz 24/7 rental but I had no choice. I took the car without having to provide my credit card information and it seemed that Hertz 24/7 was doing everything to make a wrong situation right.

I got to LaGuardia just after the cut-off time for checking bags and so we missed our original flight to DTW but was able to take the next flight out at no charge from Delta (Thanks Delta!). I also explained the situation to the check-in agent and she was very nice about the situation.

Fast forward to October 6, 2013, Hertz 24/7 sends me an invoice for $62.93 with no breakdown of the charges. I logged into my account and there was no breakdown of the charges. I called in and a rep told me that it was the hourly fee plus a one-way fee. He said the one-way fee started in October 2013. Why they are charging me that fee for a September rental they offered me free of charge is beyond me...

At any rate, I'm now trading emails with Hertz 24/7 who said the agent I spoke with on September 7 had no authority to get me any other car rental or to even offer me a reimbursement for a cab ride (glad I didn't do that). At this point, I'm disputing the charges with American Express.

I would say Hertz 24/7's business practices are questionable at best. Even if I were to be charged the rental, they are now adding a $35 one-way fee that didn't exist in early September and to this day, there is no mention of this fee on their website: http://www.hertz247.com/NewYork/en-US/About/Oneway or http://www.hertz247.com/NewYork/en-US/About/FAQ#faq_7

I think it's absurd that they come back a full month later and charge me for a vehicle. In addition it's shocking that they didn't even try to find me another vehicle before the 9:00 AM rental. My cell phone records will also prove that they made no effort to call or text me.

If you plan on doing car-share, stick with ZipCar. I've never had an issue with them and I've used them since 2004. Hertz 24/7, you just lost my business because your customer service is inept.
