I asked them what company they were with and they said "Cascade" or something like that, calling on behalf of the Oil and Gas Journal. I put them on hold while I researched the number, needless to say they hung up. Leave them hanging and I guess they move on to the next number.
Missed two phone calls with no voicemail from this number. When I answered the third call, just silence. Nobody said anything! Just rang and rang when I called back.
