I think I have correctly booked and paid my ticket on-line but I have not received any reply. What can I do?

In this case, it is necessary to contact our Call Center at +39 081 496 444.
It is also possible to send an e-mail to info@grimaldi.napoli.it, specifying the booking reference and the passenger’s last name.
A professional will provide you with information about the status of the booking and, if this has been correctly booked, tickets will be sent to you at the e-mail specified at the moment of the booking; otherwise, he will proceed with a new booking.
