Just returned a car at DUB rented from Hertz; I was very clear at every stage that I wanted to be charged in Euros, not dollars, and when I returned the car, the agent printed off a receipt with everything listed in Euros and no mention of currency choice. However, it appears that my reservation was charged in US Dollars anyway. Is this just an auto-option that they apply post-rental now (charge didn't post for like 2 days) and any way I can get it reversed without filing a chargeback?
