I booked 2 cars from Milos island for 10 days and i chose SIXT so that i deal with an international company. The terms and conditions stated that i had to contact the local company that SIXT dealt with in Milos in order to clarify i could ferry the car to Sifnos, an island next to Milos. I received confirmation that i could and when we reached Milos we were denied the option to ferry the car. I contacted Carflexi and told them what had happened and that it was no fault of mine and that they should take it up with the locals and they just said we are sorry 50 per car will be held by us... NEVER AGAIN!
