BeRebel policies expire automatically at the end of the month, but you can terminate the policy earlier whenever you want and for any reason.
Just send a request to the email address cessazionipolizza@berebel.it, indicating the reason, e.g. sale, theft, or any other reason. For some reasons you’ll have to attach proper documentation.
In the BeRebel app you will find instructions and indications of any necessary documents.
