When I booked I said car rental at O'Hare Airport. Apparently I got an Enterprise car rental about 1 hours from the airport because it was cheapest. When I went to the Enterprise rental car at O'Hare, they told me that happens a lot, but they did not offer any customer service. It was like "oh well". I asked if they could book me a car there at their location and they said they couldn't. Finally, after asking what I should do, they gave me some of their"competitor" phone numbers at O'hare location and I contacted them. Of course it was more money and we had to take a shuttle back to the airport and then over to the other agency, but we finally got the car! Terrible experience!
