I rented a KIA SOUL for the day and of course when I get there they have none available.. so Im given a cheap car that costs less than what I chose to rent at NO discount to me. Then I am given a receipt for $70 and a few days later I see that my credit card was charged for $95, the car was full on gas and no damages, so im sure its just them cheating over a customer once again. I will not be using enterprise again.
