Received a call but no message. So I called back applying the block my number prefix *67, then 1 + the 10-digit number.
Wary of this one. Sounds like a scammer either to allow them to slam your home phone provider billing your monthly bill offering a way to generate trememndous income opportunity or other get-rich quick scheme.
The robo-answering machine on the other end, says that no special charges would appear on my phone bill, etc. then starts. That, to me, was a dead give away.
