The Hertz location had an self service kiosk and agents. The posted closing time was for the self service kiosk, not for the actual office with agents. I got to the location before closing time for the office, but they were gone and closed an hour before the posted closing time. I attempted to use the self service kiosk to pick up the car, but the kiosk displayed a computer error. There were many others who were trying to pick up their car at the same (Oslo central station) location. We called the listed number but the agents initially said they would send someone. TWO hours later, we called, and the agent now told us to spend money to take a taxi to a different location for pickup and said the taxi fare will be reimbursed. There was no instructions on how to obtain reimbursement. I took a taxi to the other location, which was also a self service kiosk. Due to numerous server connection problems, it took over 30 minutes to get the car. The return location was now also changed from my original booking location and I had to take another taxi after returning the car. Overall process for pick up and return was terrible, took 3 hours and extra money for travel--absolutely unacceptable. I will not be booking with Hertz again and will strongly caution anyone against using Hertz in the future.
