The car rental service was good, very satisfied.

Very good

Downgraded car? Never heard of this before. Booked online but was told there were no cars available.

The service attitude was very good. However, the price of the reserved safety seat and the second driver's fee were three times higher than what was requested at the time of pickup. After three flights, I was extremely tired and delayed nearly three hours at the airport. Problems couldn't be solved through international calls, so I was forced to pick up the car. The rental company promised to resolve this after I returned home, but after a month, they are still stalling. When changing the car at Sabiha Gokcen Airport, the staff couldn't speak English, and there was no formal return receipt. I had to struggle to get a handwritten note in the local language. This was still with Avis.

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.
