Rented from 5 to 10 November 2014. It was a very busy week in Vegas and unfortunately National did not have the Premium SUV I reserved but the friendly agent sent me to Alamo since they share vehicles and I was provided a 2015 Chevy Suburban. The customer service was outstanding especially at the check out booth. The vehicle was not cleaned properly as I found several smoked almonds in the door and center compartments. Additionally, I contacted the lost and found department a few hours after I returned my rental because I left my eye glasses in the center compartment and I got an answering machine that told me to leave all my information and they would get back to me. I have never received a call back and every time I call the lost and found department I get an answering machine. I was very satisfied with the customer service attitude of all agents I encountered and the vehicle was great, however, due to the vehicle not being cleaned properly and the unsatisfactory lost and found department I have to rate my overall renting experience as below average.
