About 4 months ago a collection agency started bothering me by calling me at work home and my parents who live in a different state. They gave out personal information and did alot of threatining not only to me but to my family and coworkers. I did some research and decided to use a cease and desist letter. Which worked wonders. Shortly after that i enrolled in a debt management program and have made all my payments. Now the original company that i had this debt with is saying they will not accept my DMP until i revoke the cease and desist letter. What I am wondering is what would i need to include in this letter and/or why would they need me to do this? Thanks in advance.
