Finally reached this stage! Due to a flight delay and the airline in Turkey losing my luggage, I was unable to pick up the car within six hours of the scheduled time, leading the rental company to charge me the full prepayment without refund. I called the car rental service immediately after the flight delay, and they tried their best to help. Anyone who has experienced a flight delay and lost luggage simultaneously knows how frustrating it is. However, this terrible rental company showed no empathy whatsoever (I was later extorted by traffic police for 26,000 lira while driving in Turkey). I want to emphasize: I paid the full prepayment, not just a reservation fee. For those days, the car's usage rights were supposed to be mine even if I hadn't shown up on time. They shouldn't have rented it to someone else as I was only a few hours late. It was deeply unfair to not at least partially refund me. I don't want to say much more, but it's like throwing money away. It's regrettable that our great ancestors didn't manage to eradicate certain reptilian beings. Just my opinion, though many online say Turkey is a wonderful place. Indeed, I received good service elsewhere. Finally, I hope this rental company chokes on the double earnings. If you pollute the Bosphorus with your greed, Istanbul won't be as beautiful. Lastly, I wish your currency skyrockets in value.
