In August 2012, I rented a car from Hertz, Shannon Airport, Ireland. They immediately declined my Credit Card's statement of coverage and told me I had to use their CDW. This was the only thing offered and not knowing any better, I accepted it at a very pricy amount per day. A few days into the trip, I was going up a mountain when the clutch started sticking and a strange smell came into the car. I was in the middle of no where with no cell phone service, I made it to the top then coasted down hill until I came upon a house that I could walk to. It was pitch black out and terrifying to breakdown in another country with no phone. Hertz sent a tow truck after 2 hours and towed me to the nearest town to a hotel, replaced the car the next day... no paperwork was given to me, no hint of a cost for that matter. Upon returning the car to Hertz at the end of my trip, I was given a bill for 1600EUR for the previous car. I refused to sign but they said the car would be considered unreturned if I did not sign. I signed and immediately called my credit card company to dispute the charges. I was given no breakdown of the charges, my credit carded disputed it for a month and result was " I receive the services signed for". So, then months of trying to reach someone at Hertz Ireland, no response to emails, no one answers the phone, I called Hertz US customer relations. They were able to get a a breakdown of expenses, which included 220 EUR for towing?! Isn't towing included in insurance if your car breaks down?? I paid a total of 861 EUR in insurance alone! Hertz US sent me an email Jan 2012 stating that the charges only came up to 1046.40 EUR, apologized for the overcharge and said I would be credited 553 EUR. Today, I call Hertz US again because of no refund showing on my credit card and they inform me that Hertz Ireland corresponded again stating that I signed for the 1600 EUR charge and that is what I will pay. How can they do this and does anyone have any info on where to go from here. I am so feed up with this and my interest on my credit card is killing me.
