Thrifty Rent A Car review: Excessive charges

I rented a midsize car from Thrifty to be picked up in Salt Lake City Airport. A seven day rental at $375.75 with one extra day added at $49.99. When checking out with the car I was surprised to see the total charge had risen to $583.30 Concession recovery fee ? $45.74

Cust FAC CHG ? $40.00

Vehicle lisence cost recovery $4.00

TAX at 17.25% $85.82

The car was new,clean and ready to go. I drove it a total of 293 miles

Due to bad weather our venue was cancelled so I returned the car after 5 days to same airport. I did not expect a refund but I did not expect a new billing amount of $827.29. Car was full of gas and in perfect condition.

New charges were

rental rate for 1 week $585.02

Concession recovery fee ? $68.06

Customer FAC ? charge $25.00

Vehicle lisence recovery fee $250.00

EARLY RETURN Fee $25.00

17.250% taxes $121.71

Total rental for 5days /293 miles =$827.29 . They rented out the car over the next 3 days and got paid double. What a scam. !

Last note. I am Canadian so all costs here are actually 30% higher for me due to exchange rates
