Said they were with CDF

Recorded message telling me to stay on the line.

constantly calling claiming to have documents "there" they need to discuss with a family member.  Company name is DDS (real believable, isn't it?)  and the caller's name is Derrick Wayne.  When I asked if he had an actual "real" name or last name as opposed to 2 names all he did was laugh.  Refused to tell me what the company does or what the documents are for.
