The car rental experience with Auto Union in Dubai was extremely poor. The app stated that there would be a person holding a sign at the airport for pick-up, but upon arrival, there was no one in sight. When I called the rental company, my first call went unanswered. It wasn't until my second call that I was told someone would come to pick me up. The person who came to pick me up could not speak English clearly and asked me to contact him via WhatsApp. We finally met more than an hour later than the scheduled time. Additionally, besides the 2400 AED deposit, I was charged an extra 640 AED for the car rental, even though I had already prepaid through the app. The fuel tank only had two marks of fuel when I received the car, and I wasn't informed about refueling requirements until I persistently inquired via WhatsApp. Very unprofessional. When it was time to return the car, we had agreed on a time of 8 PM at the airport parking lot, but the person was almost an hour late and also had poor English communication skills. On March 27, I noticed during reimbursement that the rental company had charged an additional 26 AED to my credit card on March 24 without any notice. The charge was under the name Golden Key Rent a Car, which did not match the company name. Terrible experience!
