I rent a car Ford Focus Estate with Booking Nr. B71319326 from July 19 to July 31, 2021 with Firefly (booking No. 0BZTLG), with an agreed and written price . Accordign to the contract price I should have paid at the return of the car the remaining sume of 537 €. When handing over, the service man of Firefly confirmed to me that everything was OK. Therefore I don't understand why I was charged € 50 more from my credit card? Best regards Jana Sriencova, phone No [protected], e-mail: [protected]@centrum.cz
