We recently booked a rental car through Alamo.com for 10 days. Unfortunately, my husbands grandmother passed away while we were on vacation and we had to come home 3 days early. When we returned the car the agent made no indication of any problem. However, a few days later I was checking my credit card account and found that our rental charge had more than doubled from the price quoted in our confirmation. The Early Return Policy from Alamos website from which I booked the vehicle states: An Early Return fee is charged at a rate of $15 per rental when a vehicle is returned at least one calendar day early and total daily/weekly charges is less than the initial charged amount. The email confirmation we received from Alamo says we are charged for a weekly rate of $152.89/week + an additional daily rate. After three attempts, I was finally able to receive a fax of the invoice, in which it states our weekly rate was increased to $513.30. We indeed had the car for a full week and do not understand how Alamo can more than triple that weekly rate after confirming $152.89/week.
