I requested verification of debt owed on XXXX XXXX, 2014 from XXXX , XXXX via certified USPS letter which was signed for and accepted on XXXX XXXX. 

XXXX , XXXX did not respond to the request and has now threatened to sue me and continues to harass me in person ; they sent an individual driving a XXXX XXXX sedan to follow me when I am walking my dog and constantly take pictures of my roommate and I even after we requested that they stop.
