Long wait at the counter, no car check-in at pick up

There were only 2 people working the counter when I arrived. I waited in line for 15 min before it was my turn even though I was first in line. It took another 20 min for the person to try to upsell me to a larger vehicle, 4-wheel drive, GPS, insurance, etc. Then I had to wait another 30 minutes for my car to be ready. It apparently was the only mid-size car they have and instead of just upgrading me for free, I had to wait 30 min for them to wash, vacuum, and fill up the only Camry in their fleet. And they weren't exactly in a hurry.

Booking was easy. Not sure why the pricing changes so drastically from day to day but the price I paid was very good. There was no price drop this time after I made my reservation.

Picking up the car from Fox wasn't hard, there's a shuttle from the airport. Our car had a lot of dings & scratches, but that's not a big deal, it worked just fine. HOWEVER, returning the car was infuriating. They are not located near the other rental car drop-offs, so following signs at the airport for "Rental Car Return" is an exercise in futility (it would have been nice for the staff at Fox to let us know returning the car wasn't sign-posted). We finally found them with out GPS, and while they advertise being open 24 hours, that's only sort of true. We arrived and it took 20 minutes to find a staff person. I finally found someone we could check the car back in with and had to tell other poor customers wandering aimlessly where he was. The car return experience was frustrating.

Counter staff was very helpful.

Very easy to use.

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.

pretty sure i was double charged and this was the absolute worse customer service i’ve ever received
