I've rented a car from Budget at the Dallas Fort Worth airport a number of times over the last few months. I fly in on Sunday night and fly out Friday evening every other week. Last week, I picked up the car Sunday evening and, as before, returned it to the returns area on the top level of the rental car center parking structure. As has been noted by others, you don't typically see an agent check your car in, you drop it in a check in area and go about your day. Normally I get an email receipt in less than 30 minutes. After an hour, I called the "customer service" number on the Budget app and said I hadn't received a receipt. They said it would be taken care of and I'd see a receipt in 72 hours. On Saturday, I checked, no receipt and the rental still showed open on the app. So I called back. This time, they said they are the reservations team and couldn't help me. I needed to "return to the location" to get it resolved. I'm two states away at this point so that's not an option. I found the 972-615-4400 number for the location and called. I was given a case number as they investigate. Monday morning I awoke to find an additional $282.51 billed to my DEBIT card, not even my credit card used to rent the vehicle! I called back and was told the investigation is ongoing. There are cameras all over that facility. Additionally, I have to assume the car has some kind of GPS tracking. They have to know the car was returned and on time. It is now Tuesday and still no resolution.
