After transmitting a Certified, Return Receipt " Cease and Desist Contact '' letter to NCO Financial Systems , Inc. ( A debt collection agency - herein " NCO '' ) on XX/XX/XXXX, I was extremely surprised today, XX/XX/XXXX, nearly XXXX years after said letter was received by NCO, to have received a call from this same debt collector. The man asked to speak to me by my first and last name, asked to verify my year of birth, and then proceeded to identify himself as being from NCO Financial Systems, and that the purpose of the call was to collect a debt. After confirming that the man was in fact calling from NCO, I simply disconnected the call, and began filing this complaint.
