Caller ID says: "The Detroiters"
I called this number.  The person said my number (not name) was on a "Teamster list'. I came out of the talk without knowing the real company name, location, or business activity. I've dealt with many companies (some in Detroit)
and their very transparent. You know who they are, the location and business activity.
My brother gets two or three phone calls a day. Hopefully, someone will clean up the mess.
Until there is transparency caution is in order.
