Renter Beware of Thrifty Car Rental

For everyone renting a car please don't rent from Thrifty. We had to go out of town. I booked a car from them online. The total price including mileage was suppose to be $294. The total they charged us that day for using our bank card was $669 which supposedly included a deposit. after having it for 3 weeks they charged us $1,800 and refused to give us our deposit back. They charged us for mileage even though the site said unlimited that was   an extra $420.
