I am extremely disappointed with my recent experience at Europcar in Oviedo. We were charged an unexpected Premium Package fee of €41.91/day, totaling €304.27 for six days—an add-on we neither requested nor were informed about. We pre-paid through a third-party site for the week. During our interaction at the Europcar Oviedo Bus Station office, the friendly representative never mentioned the additional Premium charge or offered the package. She asked if insurance covered us under my booking and credit card, and I confirmed yes. I signed the rental agreement assuming it reflected the additional services I requested, which included an extra driver, not this additional, unnecessary charge I never asked for. When I raised this issue with Europcar after we returned the car in good condition, they sided with their representative multiple times. They refused to acknowledge a misunderstanding might have happened in any way. This lack of accountability and unwillingness to recognize a mistake/misunderstanding is very disappointing. I had asked for a partial refund for the additional charge or a future Europcar rental credit. My third-party booking company felt bad about the situation with Europcar (you were double-charged?) and offered something as a consolation. Not one centimo from Europcar. As a loyal Europcar customer in the past, I expected better transparency and customer care for what I see as a one-time issue where we could find some agreement. I travel frequently worldwide, and other car rental companies, hotels, airlines, and third-party travel sites have been far more understanding and gracious. I will not be renting from Europcar again and recommend others exercise caution when reviewing their rental agreements at the pick-up location and dealing with this company.
