Extremely dissatisfied!!! The AVIS rental point at Kayseri Airport is incredibly dishonest. I have had numerous rental experiences in many countries over the past decade, and this was the worst experience I've ever had. Firstly, they overcharge customers in every possible way. Secondly, during normal working hours, the rental staff were not present at their station, causing delays for customers returning cars and catching flights. Starting with the overcharging: 1. When renting a car on June 23, they charged extra by using an exchange rate 8% higher than the bank rate. Although the booking on Zuzuche was in euros, the rental company actually charged my credit card in Turkish Liras at a rate of 3.2:1 euros to liras, claiming this was their company rate. However, during our 20-day stay from June 20 to July 11, every other transaction, including rentals, hotel bills, shopping, dining, and airport currency exchange, was all settled at a rate of 2.95-3.00:1 euros to liras, consistent with Turkish banks' rates during that period. 2. At pickup, the fuel gauge showed about 90%, but the rental company employee insisted it was full, saying, “No Problem”. Yet upon return, they charged me for not returning the car with a full tank, despite my explanations. They also added charges for parking fees. On to the second point: On the return day, around 5 PM, we parked the car at the airport parking lot but found no AVIS personnel there. I called the AVIS desk—no answer. After passing through security into the airport, the AVIS desk was unattended. We spent over 40 minutes going back and forth from the parking lot to the AVIS desk looking for someone. Finally, a helpful security guard called around and found someone who told us to go back to the AVIS desk inside the airport. Carrying our luggage, we went through security again only to be told to take the car back out for inspection. This led to the situation where they charged us for not returning the car with a full tank; despite our explanations, AVIS demanded we refuel the car. Resolving this issue took over an hour, including the 40 minutes of searching for AVIS staff. If we hadn't planned extra time, we would have missed our flight. AVIS, a large company, but engages in petty tricks!
