It used to be smooth to pick up the car in advance no matter where, but this time at Hertz at Oslo Airport, I arrived more than an hour in advance and was told that the car had not arrived and I couldn't pick it up early. They asked me to pay extra to change the car or wait for an hour to complete the procedures. I ended up waiting for an hour. Ten days later, I had to go to Iceland and arrived three hours in advance. I was afraid of encountering the same situation, so I wanted the customer service and the car rental company to communicate the situation. The customer service asked me to cancel the order and place a new one, but I had to email the car rental company to explain the situation. However, I did not receive a reply from the car rental company in Iceland. Fortunately, picking up the car in advance in Iceland was not a problem, and I was upgraded to an SUV with 4-wheel drive for free. So, I have a good impression of Iceland this time, but a very bad impression of Hertz at Oslo Airport. They not only make things difficult and charge for miscellaneous items, but they have already charged me three times ?
