Rented a vehicle in Poland at Warsaw airport. Paid for and expected a compact luxury vehicle, but none available, so we accepted a larger, far less luxurious vehicle which had preexisting damages. Upon return of the rental no one present to inspect vehicle, but lo and behold after returning to the U.S. we received notification of over $500 in charges for scratches on the vehicle that we had nothing to do with. The only positive aspect of this transaction has been that their customer service did respond to my questioning the charge. They’ve done nothing to reverse the charge, but to their credit they did respond. Will never do business with Sixt again, in this country or elsewhere.
