The overall trip was enjoyable and the car was quite comfortable. The problem was at the airport during car pickup; the staff were not familiar with their tasks, causing a delay of one to two hours. We had booked two cars suitable for drivers aged 25. However, the staff on site insisted that our model (a Nissan Qashqai) required drivers to be 27 years old. Since we were not 27, they demanded an additional charge of 18 euros (134 RMB) per day, without showing any price list. (Even if the age requirement wasn't met, the additional charge should have been similar to domestic rentals, which is about 10 lira per day, approximately 20 RMB per day.) This charge seemed suspiciously high, raising doubts that the staff might be pocketing the extra fee. Upon showing him the email and the app order clearly stating the age requirement, he stubbornly insisted on the additional fee. When we couldn't resolve it, we contacted the car rental's customer service, but surprisingly, no one answered the phone calls. It was daytime and yet we couldn't get through. Instead, we got an immediate response via the app's online customer service using three phones at once. It's unclear what the emergency hotline is for. Finally, a Chinese customer service representative contacted the staff in Turkey, allowing us to pick up the car for free. It wasted a lot of our time. Seven people dragging seven or eight suitcases were stranded like fools. If there's a next time, I would likely not choose this rental company again.
