This company IS THE ABSOLUTE worst rental agency. I have spent over 17 hours on the phone with tier 2 escalations, call center representatives in the Philippines, Expedia customer support, the GM of this location who literally holds no power to make any decisions. They provided a car with an unprogrammed key fob. Agreed arriving to South Lake Tahoe, I tried to lock my car and nothing worked. I contacted their reservation dept, who then asked me to go to the store and buy a battery which they would reimburse. The battery was never the issue, so 8 hours later I managed to get the pos vehicle towed back to Reno. Now, I've been trying to get my money refunded and sixt has been nonresponsive to EXPEDIA. I have tried COUNTLESS TIMES to get refunded, but because they are based on another country, not a single person has been able to help me. I have filed fraud charges with my cc company to get my money back. I have recorded all calls, emails, etc. This will become a legal issue because of their lack of ability to provide the service I paid for. I truly hope the individuals involved with this entire ordeal experiences life changing pain. I'm absolutely fed up with this company from top to bottom. Do not rent from this crap a s s company. It's not worth the headache and unreliability. Expect the worst service and issues with your credit card if you utilize this company. To give you an idea, call their customer service to simply inquire about ANYTHING and see how difficult it is to get someone on the phone to help you. Trash.

Worst rental ever, when I picked up, not the car I requested, much smaller, charge a premium to get a larger car even though that is what I paid for. Said wait 10 minutes and the car will be ready, an hour later they finally show up. Don't drive in UK very often so got some fines, no issue, lets get them taken care of so I can pay the lower amount. No answer from Sixt, 14 days, 6 emails, 2 calls and I get told that I need to wait, so now I will pay the higher fees which are almost double and then they will add 40 pounds admin fee on to each fine just for sending them your info. Customer care never answers unless you threaten to dispute the charges. Rent anywhere but here, this is not my first issue with Sixt, they care about the money not the client!!

I am writing this review to share a highly frustrating experience with SIXT at the Denver International Airport location. My rental reservation was booked through Booking.com, and I purchased full third-party coverage through RentalCover.I picked up the vehicle late at night, around 11:00 PM, under pitch-black conditions. Due to the timing and lighting, a meticulous inspection for minor surface markings was impossible. SIXT is now pursuing a claim against me for a superficial scratch on the vehicle. I am confident that this is merely road dirt or spray from driving, not structural damage, since I noticed it later during daylight and was able to wipe with my finger the line from the front drive’s door of the vehicle. Had I imagined this would become a problem I would have wiped it off the rear door as well.I have repeatedly emailed SIXT's claims department to politely request a third-party appraisal and a copy of the vehicle’s fleet utilization logs to verify when this mark was actually recorded. Since I cannot verify if the scratch was real or not I even offered that my son, who lives in Denver, visits the facility in person to witness the damage. Unfortunately, SIXT has responded to my emails with either automated responses or with standard answers ignoring my requests for evidence while keeping the claim active. I even elevated the issue to SIXT Office of the COO but I received no answer.As I stated in the beginning, I actually purchased an insurance policy and I have coverage through Rental Cover. I suspect that in the end I will be forced to use it. However, this is very personal for me and this is why I am going to the extent of writing this review. The days of the rental I was attending my son’s wedding in Denver and this is something that created a dent in what should have been a wonderful experience and something that should not happen to anyone.Kamen NechevSIXT Rental Agreement: 9730801942

Brooke was our desk contact for our rental. She worked with her manager to get us the best price she could for an upgrade of a BMW X3. She was funny and very hospitable! Great experience at the Denver International Airport Sixt!

On most points, I had a very positive experience. The service was professional and the car was clean and met my needs. Unfortunately, my last impression changed everything. When I picked up the car the agent asked me if I wanted the pre-paid refueling option. I said yes, and the agent said Don't worry. You can bring it back dry and it won't cost you a thing. This feedback made me believe he had included the option in my rather lengthy contract. And I took full advantage and returned the car 3/8 full. However, when I returned the car, the receiving agent told me no such option was in my package and Sixt hit me for $100 in refueling. I reached out via Whatsapp and by the online review but have received no sympathy. I offered to pay the pre-paid package as we agreed, but this was rejected. I suppose I should have read more carefully what I signed, but I feel either the first agent made a mistake or he deliberately misled me in order to increase the company's profits. If this is how Sixt treats their customers I will happily go elswhere because I feel cheated.
