Rental In Palermo/trapani, Sicily

I rented a car in sicily last week 14/07 from palermo and returned it in trapani 16/07. The rental cost is supposed to be 113 € but to my surprise my credit card today was charged for 363,84 €. I havent been given any reason for this nor have I been contacted to explain. This was a big disappointment to me since I trusted Hertz to be a reliable company to rent a car from. I returned the car on time with full tank so there must be some sort of mistake here. I hope you can get to the root of this and get back to me why such a thing has happened. According to my receipt my case is RR 345668035. Best regards, Timo Kinnunen Vaaramentie 17 c 13 60510 Hyllykallio Finland +358503236000 [email protected]
