Got a call from this number at our office.  Guy was looking for people who do not and have never worked for our company.  Told him so.  I confirmed with him what company he was trying to reach.  He called right back, apparently to be sure he called the right number, but then hung up when I answered.  Probably a collection call.  We get a lot of these for people I have never heard of.

"NCB Management Services Inc" - they do collections.
