I received a call from 336-638-9000
. When I did a reverse look-up, it showed the call was from MCImetro, Ats and that it came from Greensboro, North Carolina. If they have called here before, I am not aware of it. They just hung up when I answered the phone. In the last few weeks, we have had several hang-up calls; but, it has always come across the Caller ID as "unknown number."
