I rented a car in Ireland and found two charges on the final bill that were not part of the original quote: a €30 "administrative charge", apparently for declining their insurance, and a €5 credit card fee. The car was booked directly with Hertz, and the booking confirmation email made no mention of either fee. It seems they are disclosed in the location-specific fine print somewhere on Hertz's website, if one goes looking, but they're not in any of the standard disclosures. The depth of burying makes this feel like a bait-and-switch. Hertz customer service in Ireland never responded and Oklahoma City just gave a brush-off. Any suggestions for where to go next?
