If someone is lying through their teeth over something they are clearly guilty of, it's not worth your time. You can't use reason to get someone out of an unreasonable position. Arguing further just encites more emotions, breeds further conflict, and is a waste of time. It makes a resolution more difficult for the both of you. Cut them off or wait until emotions have settled to continue.
Edit: I want to clarify that obviously you can always find a specific situation in which a piece of social advice doesn't work. This is advice for when all the reasoning and confrontation you do fails. Even if it is a necessary relationship, it's important to leave gracefully in that moment if possible, and come back later when their emotions and your emotions have cooled down. You're just exchanging anger after that.
