I arrived super tired from a flight from Orlando to Kansas City and still had to drive 2 hours to Emporia. I rented a car and hit the road. It wasn't very clean inside with some dirt under the seat. As I was very tired and needed to get to the city, I decided not to complain and continued the trip. After a while, I noticed that the dashboard showed that one of the tires was very low. The car started making a strange noise, and I decided to stop. As I was on a highway, I was very scared and pulled into the nearest Walmart to call the company. After a long wait, I spoke with one person who transferred me to another, who transferred me to another. Finally, an employee said they would send help. I said "great, because I need to continue my journey." After an hour and forty minutes, that's right, almost two hours calling the company non-stop, asking them to help me, I did not receive ANY response. Since I couldn't wait because I had to continue my journey to work the next day, I drove very slowly on a dangerous highway back to the airport to exchange the car. I did so. The employees there (Lydia and the dark-haired guy who receives the cars) saw my state: desperate, sleepy, nervous because I hadn't received a call from the company, and crying. I got another car and continued my journey. Soon after, I noticed a charge on my bank account. They had charged me for 1 day of rental, even though I just exchanged the car and still had the rental for the next 5 days. When I called the company to complain about a series of things (service, car maintenance/check, etc.), Mrs. ALICIA DIXON answered the phone and very rudely said the following: It's your fault because you didn't pay for full insurance. If you had, you would have gotten help. I replied that the car probably wasn't properly checked because besides being dirty, the tire was low (or even flat), as I noticed this a while after starting to drive it. She continued saying that I probably drove over something that punctured the tire. My God, the company offers cars with problems and dirty, and still has a manager who blames the customer for the car's issues? When I told her I would record the call because I couldn't believe what I was hearing, ALICIA DIXON HUNG UP ON ME. That's right. A manager who HANGS UP on the customer. That's when I understood that the whole company has problems, and no consumer should go through this. I gave up talking to anyone and returned the car as soon as I could go back from Emporia to Kansas City. Today I received a threat by mail from the company saying that I still had the car (the one that was returned the same day because it had a low tire) and that if I didn't return it, they would report the car as STOLEN. Folks, if you want to have problems, be called a liar, have the phone hung up on you, and still receive a threat from a company (that has serious problems, besides communication and organization issues), this is the perfect company for you. Now, if you want to be treated with a minimum of respect and have a car you can trust for safety, maintenance, and inspection, NEVER USE SIXT. Because if you still have a problem and ask to speak with a manager, like ALICIA DIXON, she will call you a liar and hang up on you. A TOTAL disgrace!!
