I booked and paid the rental of a Fiat 500 for less than 24 hours at a price of 94.66 €, end of March for 13/14 July 2019 in Avignon, 3.5 months in advance. I made the car clean, in the same condition, in time, with the full, so without any problem a priori. The 18/07/19, I am charged 18 additional euros Hertz. I then contact Hertz for explanations, knowing that I have not received any invoice of this amount. After relaunching 4 times until the end of July, and left my details to understand why this surplus of € 18 was improperly taken, too late to oppose. I still have not been contacted and refunded. What is the point of paying in advance and then being overcharged for no reason? Thank you Autoescape, thank you Hertz !! Nice scam !!!
