Dynamic Recovery Services complaint

This company call a relative's job asking for me. She told them I did not nor did I ever work there but she was a relative. She asked them who they were and why they were calling and how they got her work number.

They said it was for a Discover Card debt I owed from 2000. She said the SOL was out on that debt. He told her he "assumed" it would be paid and he did not know if the SOL was out or not, he has to know if he is a debt collector.
