This is a energy brokage company. Wanting you to invest in energy prospects. If you call it back your can get taken off there calling by entering 2 when you get the message.
I asked this guy his name, and he said "Brian Caldwell" of "Caldwell Resources". When I asked where they were based, he wouldn't answer, so I hung up. My caller ID said "Sethi Financial". They seem to be based in Plano, TX (from googling the number).
I have received repeated calls from this number, showing Office Manager on the caller ID -- there is never anyone on the other end, but today I called the number back (after determining that area code 972 is domestic) and hit 2 to get my number off the list.
