We rented a car in Amarilo Airport. By the time I arrived to the hotel, the car was making a very loud wheel bearing noise. I felt unsafe and that's when I decided to call interprise to inform them of the situation. After all the confusion we come to find, Interprise IS NOT OPEN ON SATURDAYS. After calling several times, finally customer service finally got us an Uber, back to the airport. Upon arriving Natinal Rental was able to help us, but after so much back and forth finally was issued a car. We were calling all morning long to make contact with interprise, CLOSED. This is a TOTAL inconvenience. We weren't able to get started on our vacation till all this matter was cleared. NOT OPEN ON SATURDAY?????? What would have happened if we were stuck out in the middle of a Texas desert and heat
