when arriving to Sixt in TLV i was informed that the Travelocity order is not confirmed by SIXT. I have received clear confirmation form Travelocity and since i never got any cancellation, I called their client service and asked for help. (Their international number is not available). the support agent confirmed that the order is valid and asked me to wait on the line for further checks. when i asked to return to my local number she refused (which means that Travelocity support for international travel is dubious). After 30 minutes of international call she failed to provide any solution and still asked me to wait on the international call. I have refused and asked to get a written answer. since i was already one hour at SIXT, i have rented a car at the counter for double the price and lower class.
