this is portfolio recovery services. I answered it once.

Receive a call from 800-861-5065 (CNAM UNKNOWN)asking for someone with the same last name as I, calls every Monday.  Recording ask to hold if you are the person or to call 1-888-716-0000 if the person does not live there.  I have no idea who the person is they ask for, but I refuse to call an 888 number for any further conversation.

I received a call followed by a recording asking for someone with a similar name to my own.  I chose to hang up.
