I've rented a vehicle at Europcar via your site, which I've done before. Upon arrival the lady at the Europcar counter asked me for my US creditcard. I am a Dutch citizen, which is also what I indicated when making my booking. (mandatory) Because I did not have a US creditcard I was asked to pay 830 euros extra. Due to mandatory insurances and the difference between EU creditcards and US creditcards. I've told her that I'm in their system, rented vehicles before and how on earth I can be seen/registered as a US customer and she told me it had to do with the IP address that was used when making the booking. She also told me there was nothing she could do for me as I booked via your site. Very bad experience overall and additional costs that exceeded with over 100% of the initial booking costs
