Customer service needs to work faster. The pickup process took almost 1 hour.

The first car they gave me was not cleaned both inside and out and had a loud humming noise in the back rear tire. I went back to Fox the next day to get a different car which was cleaned. I wan not given a credit for the first day. I also returned the car a day earlier and they did not give me a credit for an early return but charged me $20.

Make a easy drop off sign or box. Many of us were waiting in line for drop off until after many minutes, someone said drop the keys off and go...so making that a more smooth operation would be helpful. Also, I think the car I was driving needs a wheel alignment.

I waited over an hour for a customer service agent. This has never happened in my life at a car rental agency. Once I got to customer service it was very fast, the agent was very courteous, professional, and efficient. He was one of 4-5 other agents, but the other agents seemed to take much longer. This appeared to be part of the extreme wait time. I also did not get the car I wanted. I reserved a 4-door sedan, but got an SUV. I was so tired and hot (it was 90 degrees in Denver) from waiting that I didn't even ask for a different car, I just wanted to get out and leave. Drop off was much faster, but I noticed that the line for others to get their cars in the morning, was just as long as it was for me in the afternoon when picking up the car. The shuttle to the airport was ready and waiting.

Ridiculously slow service from pickup at the airport to check in at the counter to waiting for the shuttle after drop off. Not worth whatever money I saved going through Easyrentcars.com

Vehicle was extremely dirty inside and out. Also, for pre-paid fuel option, would give customer's to refuel in case they did not use as much as gas as they thought they would. Everything else was great, thank you.
