I hated every moment dealing with National. Upon arrival, the employees at the counter didn’t bother asking us for our reservation information they just turned us and the other clients away. Not only did they sell our reservation, which we had done with more than two months in advance, but they offered no type of solution or assistance to the problem THEY CREATED. Their cavalier responses were “try booking with another company” or “Uber to your destination”. No one in the counter really made an effort to deal with myself or the other clients who were also left screwed over by their poor management and decision making skills. Each and every single one of the employees just dumped the issue to the next until finally they pulled a lame excuse out of their asses as to why they wouldn’t even try to help us. They wanted to hold on to the fact that “it was late at night and they couldn’t do much.” I did take their advice and took my business elsewhere, and the lady at Avis went above and beyond to help me and my group of 17+ get a car to get to our destination. She did not care that it was past 3am and her shift had ended. She did everything she possibly could as a simple customer service associate to help me and my family. Something that EVERY SINGLE ONE of the National employees claimed they could not do because “it wasn’t in their power” I wouldn’t make a reservation with National or it’s affiliates even if my life depended on it. Definitely will tell every single person I know that National is by far the worst company to rent with and the customer service offered at the Denver International Airport location is so poor, that Satan himself would feel offended.

Poor|Feb 2022
Our flight was delayed and when we got to National to pick up our vehicles (we had 2 different reservations), THEY HAD NONE! It was past 1am and the only thing we were told was "I'm sorry", "there is nothing we can do about it", "go to another rental car place and see if they have anything available". THIS IS UNACCEPTABLE AND UNPROFESSIONAL; CUSTOMERS DEPEND ON THESE RESERVATIONS WHICH ARE DONE MONTHS IN ADVANCE, TRUSTING THAT NATIONAL WILL HONOR THEM. IT WAS A PARTY OF 17 PEOPLE AND WE WERE STRANDED, IN THE COLD, AT 1AM, WITH NOWHERE TO GO AND NO REAL HELP FROM YOU. WE WILL NEVER DO BUSINESS WITH YOU AND WILL NEVER RECOMMEND YOU TO FRIENDS AND FAMILIES. DO BETTER!!!!!

We had to wait about 45 minutes to get our vehicle due to the rental car shortage but they were kind enough to upgrade our vehicle and take a day off our rental cost. It was unfortunate but they provided good service under the circumstances!

They were very busy at pickup. They were working hard but could not keep up with the arrival rate.
