This was the most unpleasant car rental experience I've ever had. The paperwork process was fairly smooth, taking about 30 minutes to complete. After picking up the car from Cizgi, we drove about 20 kilometers on the highway and were hit from the side by another vehicle. The other driver got out, apologized, and admitted full responsibility. We called the police together, but after waiting for several hours, the police never showed up. During this time, I also tried contacting Cizgi via the emergency number printed on the card provided during pickup, but it was always an automated response followed by disconnection. I want to ask Cizgi: why provide an emergency number that doesn't work? Isn't that deceptive? I also sent an email to the address printed on their card, but there was no response. After waiting for hours, we had no choice but to return to the Cizgi office. In the end, they forcefully charged us 22,000 lira. While it’s not Cizgi’s fault that Istanbul police didn’t come to handle the situation, the fact that their phone didn’t work and emails went unanswered shows that Cizgi is an irresponsible rental company. If anything happens during your trip, such as a breakdown or requiring emergency assistance, you will have to solve it on your own. I strongly advise against choosing a rental company like Cizgi just because it seems cheap. If you encounter issues, no one will help—you'll be left to fend for yourself.
