Got a call from this number this afternoon, it sounded like a predictive dialer as no one was there when I first answered and then a young man came on the line and said "how are you doing??" very friendly...I asked who was calling and then he asked if this was "the china shop" and then hung up.
Just received a call from this number and it was the same MO as yours with the exception that the young man asked for a persons name. I said that person was not here and could I take a message. He said no and hung up. I don't like the sound and feel of this caller.
APS CAG is what showed in the caller ID. No clue. Googling, there's APS International/Civil Action Group, whatever the heck that is. They surely have nothing to do with a small contracting business 1000 miles away.
