  HORRIBLE HORRIBLE HORRIBLE. My flight was delayed so I tried to contact customer service to see if they would wait for me. The lady on the phone was short with me explaining they will not wait. I called back for another rep and she added my light to the roster, she said they will wait up to 30 mins. I arrived at the airport just in time and managed to make it to the counter 10 mins before close. The gentleman at the desk was the only nice thing about the whole experience. The woman who gave me the keys for my rental was very rude. I barely understood her instructions. They gave me a dirty car in the dark and expected me to do my own walk around in the dark in the middle of the dark airport. Did I mention it was midnight in the dark!!! My drive to my destination was over the 1 hour time limit given to report any found damage. It was parked at a funeral home and I drove back. There was no curb to rub or scratch the rim. Now you all claim I damaged the rim yet you provide no evidence that I did it. I have pictures of the vehicle and see no damage on the car. But of course I am being blamed and charged for it. I will never ever use your company ever again. There was no one to check the vehicle with me at drop off to verify this claim. Worst experience ever.

  Make sure and take photos before and after you return any car rented from this thieving company. They claimed damage after the car was returned early morning which did not occur during our rental and charged us $2600 for what looks like a scratch. We have had cars damaged at the Milwaukee Airport before. The car was not damaged during our rental period. This company does not care about their customers or repeat business. They’re just money grabbing thieves.

  Unfortunately this location was pretty disappointing. It is a very small Sixt location and they don’t have a lot of premium vehicles, so if you're hoping to get what you booked lower your expectations. The rental counter worker has an unhelpful attitude, and seems to not be able to read numbers as we were told we were getting a car with 1800 miles yet ended up with one that has 18000. Since there aren't many cars you also shouldn’t expect to get a clean car in pristine condition like other Sixt locations, it will most likely have some level of dirtiness and damage on it. My experience would have been 1 star if it wasnt for the ladies at the key pickup and return. They were very kind and nice.

  I recently took a trip back to WI for a family gathering and rented a car with Sixt via Expedia. The associates working on the day of my rental all deserve a shout out for being incredible. The check in was a bit delayed as two groups ahead of me were having issues. But they were kind and helpful to them. I ended up getting an upgrade as the SUV I chose was sold out. The associate realized I was having issues familiarizing myself with the new tech and came over to help me connect my phone. When I returned, the girl who checked in my car was also amazing. I let her know I noticed a slight cigarette smell and really just wanted to confirm it wasn’t me. I ended up getting a credit towards my next rental because of this “inconvenience”. In all my years renting vehicles I have never dealt with such a professional, friendly staff.

  I strongly do NOT recommend doing any business with this Sixt branch at Milwaukee after my absolutely horrendous rental experience. Never seen a catastrophic failure in administrative customer service so poor, negligent, and outright insulting in a service. After a 2 day rental of a BMW X5 that I paid premium money for, I filled up the car with premium fuel (didn’t have to do this btw! But I wanted to be a good client and respect BMW cars!) to a full tank before I returned the car. It was 1 hour early from agreed return time and I handed keys to a kiosk employee with what I thought was the end of a supposedly “good” rental experience. But the horror began when the Sixt app showed it was overdue +8 hrs after my flight home. I called Customer Service to let them know I returned the car. Next day, someone from Sixt called, i missed it, and left a voicemail that said its overdue for 2 days now. You can’t dial this number back. Called customer service again, and although they see that the car is “not returned”, all they could do is send an email to the branch manager. Further emails with Customer Service just shows that they really can’t do much, or even talk to branches directly, and I think this is a terrible communication flaw and horrible customer experience dealing with the stress and lost time dealing with an issue that could easily be fixed. After looking everywhere online, there is NO way to communicate directly with the Milwaukee branch; I have to believe this is intentional by design. After 70 hours of the car being “missing”, the booking finally closed with a final invoice. But to my absolute shock and horror: I was charged an additional rental day and a TWO HUNDRED SIXTY DOLLARS ($260)!!! What an outrageous and major error! …could you even call it an “error” or is this borderline intentional malice and fraud? I have had NO communication with this branch at all and i have been struggling to communicate with customer service for refunds, which is somewhat proceeding as we speak. But overall: NO customer should go through the infuriating inconvenience of being accused of not returning a car and not fueling it and then dealing with poor communication abilities of an off-site customer service and not being able to communicate with the branch itself. But if you have to: Take pictures and videos! the entire car (read other reviews about damages), the dashboard, fuel Reciepts, geo-referenced and time-stamped locations on where you dropped it off, the fuel gauges, get the name of who’s taking your keys, etc. But I would never want to relive this experience ever again, and I would advise anyone else not to. To the branch management of Milwaukee Airport: HELLO! I wish it didn’t have to come to this and I wish I got this resolved internally. This is hilariously probably the only way I’ll ever be able to hear from you: a 1 star review. So please do better! I still do like the premium car availability of Sixt. You are absolutely not living up to the premium brand experience and I will not be renting from you ever again, and I have lost trust in every other branch in the nation and must take the necessary precautions that I listed above. Bye.
