Enterprise Rent-A-Car

I had reserved a car for the Tuesday after Memorial Day weekend. When I called that morning to ask to be picked up from my hotel, no one answered. I re-​checked the number and called again; still no answer. Then I called the toll-​free number for Enterprise, and when the operator tried calling over, SHE got no answer.
So, I made other arrangements to get myself over there. Indeed, the office was open that day. And as I waited in line, guess what I heard? Their phone ringing in the back over and over– and no one answering it!
I told the agent about my experience, and that I had to pay my own money to get to the office, and he agreed to give me a small discount off the rate. And he did apologize, saying they were very busy that morning.
I’m pleased with the agent’s response. But guys, if you’re reading this: REALLY, you NEED to answer your phones. I don’t care if there’s a line of people out the door; bring in another staff person. What if there were an emergency and someone– the police– were trying to reach you?
That said, my car was fine, and they did drop me off at my hotel at the end of the reservation, which I didn’t expect (since they don’t advertise that). And all the staff members I interacted with were polite.
