no caller id so I dialed *69.
called the # back and never get a live person just a recording saying ACS, Inc., leave your name and number and we will call you back.
It is not a professional type message either. Sounds like a collection outfit but no collectible debt here for years and years.
Reverse trace on whitepages.com shows it to be in Royal Oak MI.
There is a computer technology company called ACS but at some point you would get an answer or a professional type phone computer voice giving a company directory or a prompt to dial your parties extension if it was them.
Anyone dealt with this outfit before?
