This is almost more of a relationship issue than a golf issue. A guy I used to play with all the time cheats and is very defensive when called on it. He's also quick to call various other people cheats, including Dustin Johnson after a certain incident at a certain major. My solution has been to stop playing with him (and largely to stop hanging out with him, although other reasons went into that).
