Really horrible customer service ! !
I originally wanted to use the car for 9 days, but had to change my flight to return after 7 days.
When I told the people at the counter, they changed my contract to return before opening hours on the 7th day, which I did.
I was charged for the entire 9 days. Apparently they billed me for the RESERVATION, and not the actual rental period on the contract. I had some verbal talks with their customer service people who promised me verbally that the extra two days would be refunded. So far, no refund has been processed.
Unfortunately, every time I book Southwest Airlines into Charlotte, they expect me to add on a car from this company. so I will from now on avoid doing business with them again by booking the car separately.
