Our goal is to make searching as transparent as possible. That's why we give our deals a rating based on what the policy includes (e.g., fuel & mileage, insurance, and cancellation policy). It's worth keeping in mind that the final price you pay for your car rental may change because of additional options offered by the car rental provider, such as additional driver, GPS, and insurance options (although these should always be optional).
If you still think you've been overcharged, we recommend you contact the car rental provider you booked with. Skyscanner doesn't have any access to your booking information, so the provider is best placed to help investigate.
We've put together this handy list to help you to get in touch with the travel provider you booked with.
