DO NOT RENT HERE UNDER ANY CIRCUMSTANCES…read more I prepaid through Expedia for a rental car with Sixt at Düsseldorf Airport. My flight was delayed by 2 hours, but Expedia confirmed with Sixt that a late-arrival note was added to my booking. When I arrived at the counter, the agent acknowledged my reservation but refused to honor it unless I paid nearly €500 more because they were out of cars. I declined. Instead of resolving the issue, they marked me as a "no-show" and won't issue a refund, even though I was standing at the counter with proof of my confirmed booking. I was left without a car and had to make a new reservation for a later date at additional cost. This is not customer service, it's a scam.

The car rental company did not have the vehicle available and said it would not be available the next morning either. They claimed to not have another comparable car but offered us an Audi at a hugely increased price. The only additional charge we should have incurred was $63 for one additional driver. At 10:30 p.m. on October 14, 2016, we had no choice but to accept the vehicle at the outrageous fee. I have never incurred such a situation although sometimes a requested car may not have been available but an upgrade was provided at no additional charge. The car rental company took advantage of us and I will never use them again or refer others to them. It was evident Sixt rental car company doesn't care about customer service when their manager at the airport location didn't provide a simple apology for this huge inconvenience at the time and as we have still never even got a response back from the company headquarters when we have contacted them about this issue. We were forced to absorb this astronomical charge and will continue to ensure anyone we know looking for a rental car company is well aware of this issue & their terrible business operations.
