The car had been reserved in downtown Chicago, even though I specified O’Hare. The person at the desk at the airport said she couldn’t get the reservation switched over to O’Hare and was not very helpful. I called Hertz customer service and they were outstanding. Got the reservation switched and a better price, even! She was so helpful and kind which was so appreciated after a 5 hour flight with and infant and a three hour drive ahead of us. The check out/check in process was totally fast and efficient! Will definitely use Hertz again! Thanks!!

Staff were extremely polite and accommodating and this is the one redeeming factor. It took about an hour waiting in line to reach the budget counter. Seemed like everything went fine until we reached the garage and found out we were given a Ford Runner with terrible mileage for hundreds of miles of turnpike driving. Representative in the garage tried to help us out and moved us into a Chevy Malibu. Unfortunately the car was dirty (obvious trash left in car), but we were willing to deal since we were already severely delayed. But then we reached the garage gate to checkout and found out from the attendant that one extra feature we asked for; an Ezpass on the rental, was MIA. It was just one issue after another and overall a very bad experience, but again shout out to the staff who were very kind and helpful throughout.

Desk person asked if I wanted the Fuel deal to return it empty. I said no, I'll fill it up. She charged me for the fuel deal anyway and I didn't realize it until I turned the car in. Trying to figure out how to get my $66 back that I should not have been charged. Also, the line was 40 minutes long just to get to the counter. The actual car was fine, but the Dollar service is not good.

Poor|Jan 2023

My flight was delayed, and I arrived at the dollar counter, just after they had closed. There was a lady still behind the counter, who informed me that because I had not arrived within two hours of the predetermined time they had rented my vehicle to someone else. How is this practice even legal being that I had already paid for it? I was forced to take rideshare to my destination and then back again the next day at an expense of more than $120. I am quite sure that I had pre-purchased insurance but dollar could not confirm this so I paid for insurance that I didn’t need , my total charge at the counter was an additional $124.22. The type of vehicle I had requested was not available so I had to settle for what they had. There were four shirts laying on the back seat, so I find it difficult to believe the vehicle had been cleaned , I think that the previous customer had just left it clean. Please let me know how to get a refund.

I had to trade my first car for another one because I was getting tickets due to the fact that the license plate had expired a month earlier. Both times the pick-up process took forever. The only place to sit in the dingy office is a ledge along the windows. The staff (only two people) was very nice and helpful but clearly overwhelmed. Even though this office is only four blocks from where I live I'm not sure I want to rent from them again.

From check in to drop off the experience with Payless rental was horrible! Car was not full of gas all though the paperwork stated it was. Car was dirty (literally trash left in the car), waited in line for pick up for almost 40 minutes…there were only 3 customers in front of us. Had issues with the car immediately as back passenger tire was not keeping air. At drop off they told us there was nothing they could do and that we’d need to call the customer service line. Customer service told us they could not refund our money because we booked through a 3rd party. I would NEVER use this service again or Payless car rental! It was HORRIBLE!

The pick up experience at Payless in Chicago was horrible. Our car reservation was for 6am right when they opened because we had had a nightmare travel experience and needed to get home as soon as possible. There was nobody at this time. We waited around for a while as we saw employees arrive for all the other car rental companies. After about 15 minutes and still no one there to help us, I ended up finding a Budget employee that was able to assist as best she good. She reiterated several times throughout the process that Payless does things a little differently than them and she was unfamiliar with their process. Long story short, she ended up miscommunicating something to me (not her fault - she wasn't a Payless employee), leading to an expected nearly $100 charge on my card. The silver lining was that Payless Customer services was very nice after the fact via online inquiry. Quick responses, understanding of my situation, and accommodating to my requests. Although I had a good experience with customer service on the back end, the negative experience I had on the front end is enough to make me not use Payless again in the future.
