Hired a car, collected from Sixt and was advised of extra insurance which I declined and everything else covered. Didn't select any additional options. Had to give my credit card as down-payment of £1000 in case there was any damage to the car. Returned fine, no concerns. I was advised there were no additional charges. Few weeks later they charged my account £60... Rental cars gave me the runaround as they said it was Sixt's problem and surprisingly Sixt did the same... £60 extra for insurance that I didn't request and a fuel charge that was apparently included in what I paid for already. Would never book with them again!
