never left message

Automated message to: "Please call 866-319-8596." They call every day around the same time with the same automatic message. I'm not convinced that this call is really directed at me, since no identification of any kind is provided.

The call my work phone several times a week looking for a previous employee.
The automated recording identifies them as "jc christensen and associates", a debt collection firm.
Unfortunately it's only an automated call, and they don't leave a callback number, so I'm not really sure how to tell them the person they want is no longer at this number.
It is very annoying.

I get this call often also, Identifying as JC Christensen and it is imperative they receive an immediate call back. Never asks for anyone specifically.
I know that I do not have any debt, so I am chalking it up to wrong number

They just called me on a Saturday morning, rang once and hung up.  No message or anything.
