The customer service actively recommended insurance and GPS upgrade, but later calls couldn't get through.

Apart from the car pickup, everything else was acceptable.

Good

This was the worst car rental experience I've ever had. The staff tried to upsell and change the car model, which incurred additional costs. However, since the price increase was not significant, I let it go. I explicitly requested not to use a credit card for payment and asked to use a Euro bank card instead. While I was getting the money, the staff locked the door and ended their shift, ultimately charging my credit card. Communication was completely ineffective, and I was repeatedly hassled. It was extremely unpleasant.

The hertz desk was busy lots of people collecting vehicles only 2 members of staff dealing with customers. Could have been quicker as a hertz gold member I am used to faster service. They have also made an additional charge of €82.40 which I am currently disputing and require further explanation.
