Just want to share what a horrible experience I had with National. I proceeded to the counter at National waited about 4 people ahead went to the lady at the counter who said my rental was with Alamo. Now I know I booked National she said it was an Alamo car and nothing she could do, no manager on duty etc. So then lugged all the luggage with 2 small children in tow to Alamo line about 30 people deep. My husband stayed in line while I called the 800 # to National the operator confirmed I had a National car as I already knew, so then I went back to the National line. The other "rude" person there checked again and sure enough there I was a National rental car. I at this point was so overcome with anger that they had me wait in 3 separate lines. She said no mgr on duty was as rude as could be and then charged me an additional 20 dollars over my original quote. I tried calling the direct # to that location to complain during the week without any success so I will write a letter to corporate and go back to Dollar even if it is slightly more money. As I found out customer service is not in their favor.
