This is what you do = particularly if, as in my case the statute of limitations is over. WRITE A LETTER ...cease and desist ~ stop calling contacting you in any way. My letter stated that should they contact me again, under the Fair Debt Collection Practices Act (FDCPA) each call is a violation subject to my obtaining $1,000 per violation, which I will not hesitate to pursue..and by the way the 9 year old debt - $400 my ex husband owes.
