I also got a call from this number and when i called back it said that this investigation department does not accept incoming calls. I have no clue

who are these people

They said they got a hold of someone in my unit but wouldn't tell me anything else

A Phone message was left for my son on his dad's phone.  The lady leaving the message spoke loudly and fast.  Some words were garbled.  She never left the name of the firm she was calling from.  She said an order was sent to (a lady she named) office with charges claimed against my son.  She wanted his phone, address and work information. She gave a claim number with a number to call:  855-733-9196.  I called the number .No information was given on the identity of that company.  A message played saying if you know the extension, etc., otherwise dial 0 for the operator.
This reeks of a scam to me.  Anyone else have this happen?
