Hertz Rental, I rented a bike for 5 days in Madrid. I paid for unlimited milage., When I arrived they said I had not paid for unlimited mileage. As I did not have All my paperwork with me, I could not verify this. On my return I complained. I did not get any help at all locally or national as they wanted a K or L reference number and my reservation had neither Make sure you take all paperwork with you when dealing with the bump price vendors (like rental and budget airlines) Otherwise you are easy prey.
