Presumably those that are calling you are people who are his friends and relations and therefore not "on your side" to begin with. As best as possible, just ignore these people and even hang up on them without discussion because there is likely nothing you will say that will "convince" them of the position you are taking in the matter. If any of them make threats or act in a physicall threatening way then do report that to the police.
