If for any reason you can’t pay a fare, the driver is required to terminate the ride with the note “not paid”. In this case, the customer account is automatically blocked from making further bookings. The block can easily be removed by our customer support team as soon as the fare is paid. Customer support enquiries can be made via support tickets in our app (under Feedback & FAQ in the app menu) or via e-mail at support@clevershuttle.de.
