DO NOT USE! - This company is not good. I am going to leave this review on every site I can find. This was my first time using this Sixt for business travel. Never again. The booking part was fine. However, when my flight was severely delayed I tried to call into the branch location at the airport I was flying into. They were only open until 1am and I was scheduled to land at 1am. You CANNOT reach the local desk at the airport! I called the corporate number and got someone that spoke next to no English. Its one thing to use offshore customer service people its entirely another to have people that simply cannot speak English. She was zero help - I asked to speak to a manager or someone that could understand what I was saying - she WOULD NOT put a manager on the phone because she kept telling me 'I have satisfied your request' - that was not the case. She did not address the issue or provide any level of assistance. I asked for her name and ID number - she refused to give either one (this was after she refused to put a manager on the phone). I hung up and called back. The next person was very polite and informative. HOWEVER, all the information he gave was incorrect. He took my flight information and told me they would notify the branch location and let them know I would be arriving late so someone would stay to help me. He also recommended that I check in with the mobile app so the car is ready. When I arrived at the airport. NOONE was there, no car was there and no one answered the phone at the corporate number. Now I don't have a car, looking for a hotel at 2am and I am sure they cancelled my reservation and will have to deal with that in the morning. USE AT YOUR OWN RISK
