I am very familiar with Sixt being from Germany. It’s a German company. I have always rented cars in Germany but never used Sixt in America. Germans have a higher standard than Americans or at least Nashville airport.I had a reservation for a car and upgraded to a higher SUV due to the hubs knees. When we got to the counter I showed the lady and she said we don’t have that car. I kept getting confirmations that I was all set. She tried to find a replacement and found a BMW suv. If you are familiar with this vehicle it’s the same height as a car. The purpose was for the height to get in and out. I drive a Ford Expedition so I was planning on that height. She kept trying to say but that’s an upgrade. I TOLD her BMW doesn’t impress me I need a higher car. She finally found a Dodge Durango and I said yes. We walked to the booth and handed the lady our information. The first thing she said was did you go to the counter or register on the app. I said I went to the counter and the lady helped me with the app. She seemed disgusted. I also mentioned I accidentally chose the return time as 10am but my flight isn’t until 3pm. All she said was it will probably charge you for another day. I said can we check to see if we can change it to 12pm. She wasn’t going to offer to check. She checked and said it’s more money. I said forget it I will do it on the app. Took the keys and got to the car. All is fine we drive to our hotel. We start getting our stuff out and we start seeing garbage that was left in the vehicle. That took the cake. I can deal with rude people but rude people and garbage in a rental car is unacceptable. I’m embarrassed for the German company. Sixt do better with quality control. Your employees lack of customer service and not cleaning vehicles will put you in the ground.

Never book with them. Their advertisements are false. Their customer service is nasty. They are having us sit and wait 20 minutes because we got here 20 minutes early. Car is ready. He tried to upgrade us to a car were gas mileage would be double. Don't trus rhem

I set up a rental car reservation online with Sixt Rental Car, at location in Downtown GA (133 Luckie Street). Got my confirmation #9738413007 and was quoted $137.71 for the day. My family and I had to walk 15 mins to get to the location. When we got there, the agent told us it was over $800 for the day. I stood there and stared at him and ask him, did you really just say $800???? I proceeded to show him my confirmation email with the quoted price and he checks and again and same thing. I told him there must be a mistake and can you please call someone or do something to help me. First of all my quote was not being honored, second who is going to pay over $800/day for a regular rental car?? He basically looked at me and DID ABSOLUTELY nothing. My family and I were visiting GA from NY and now here we are stranded in the middle of nowhere with NO CAR and this company and employee did NOTHING AT ALL to assist and let me and my family just walk out of their business. I now just feel this was major price gouging. I just want this complaint to be posted and know that this business is a rip off and practicing bad business and not helpful at all. ABSOLUTELY RIDICULOUS that this was even allowed and that their employee DID NOTHING and was basically ripping me off!!!!!!!!!!! PLEASE be careful if or when you set up a quote online!!!!

DO NOT USE THIS COMPANY! I made a rental car reservation through Expedia with SIXT for $352.67 on March 5 at Atlanta Airport. Due to a flight delay, I was informed that I needed to cancel and rebook the reservation, resulting in a new charge of $896.43.At the SIXT counter, we explained the situation to Victoria, a customer service representative. She advised that she could cancel the rebooked reservation by contacting Expedia by email and rebook us at half the cost. Relying on her guidance, we proceeded accordingly. She lied and knew she was lying.I contacted SIXT customer service and was explicitly informed that Victoria’s statements were false. In the call, which I recorded, the rep said Victoria lied. In other words, this was fraud, and as a result, both charges—$896.43 and $534.60—remain on my credit card. Neither Expedia or Sixt will help. They take no responsibility even though it clearly shows two bookings for the same time.

We rented a car from Sixt’s ATL location. We had no problems with the car and returned it on-time and without incident. The attendant checked the car and our deposit was returned. Over a week later, they started emailing us about damage to the car. We disputed the claim, as no damage was done to the car while in our possession. It’s been 15 months (and countless emails) and we’ve gotten nowhere with them. They use AI and automated responses and you cannot get through to a real person. Now they are threatening to send a collection agency after us. A quick search online will reveal how widespread this practice is with this company. They’ve been sued and fined millions for their fraudulent practices. Do NOT rent from them!
