We had clearly informed the rental company that we didn't need their additional insurance. Despite our knowledge, they inexplicably charged us over 100 pounds for insurance. During the pickup process, they indicated that we should pay extra to upgrade the car. We had booked a Mercedes C-Class, but when they learned we didn't want an upgrade, they gave us a Mercedes A-Class, causing a series of changes to our plans. Thankfully, the customer service at Zuche stepped in in time to prevent further losses. Overall, we're very disappointed with this rental company.
