A ';collection'; company Pallisades New York call with intimidation on a 12 year old discharged debt?

Debt removed 12 years ago. Not 2 or 3. In CA the limit is 2 years. My lawyer says just tell them they are in violation of the law and to go away. What do you say? If you have no experience in this, please just keep your ';opinion'; to yourself. I am looking for real experts here. Thanks very much.
