Usually, if there are no similar vehicles available, other companies provide the same or a higher class car. Hertz replaced my Mercedes C-Class with an Audi Q3 and told me they were the same class, which was very unsatisfactory.

The staff were rude, seemed like they had an argument with someone earlier

The procedures were clear, the process was smooth, and everything was great.

The service attitude was average. They insisted we rent snow chains, which added 60 euros to the total cost. They scared us by saying we would be fined if caught by the police without them. When we wanted to store our luggage for a few hours when returning the car, they refused.

Your system didn't inform Hertz about the last minute price reduction, so it took almost an hour to get the right price.
