Must be Enterprise Car Rental - just rented a car a few days ago. I didn't pick up, they didn't leave a message. Too bad, I had a great experience renting from their location in Portland.
received call from this number but didn't answer. they left no voicemail, but I saw the post above about a customer service survey from Enterprise Car Rental and I just rented a car from there two weeks ago. That just might be it.
