left a message on our business line just like in John's comment. Could only make out her name, Danielle S. She spoke fast and left her name and number.
I called this number and it only said to leave your name and number. Won't be answering any future unknown/private caller.

Just received the same cryptic message as above.  Scam artist.

Same as the above. Scam artist. Google came up with "Danielle Seadia", some b-grade voiceover person: http://www.danielleseadia.com/vitals.html. Annoying person.

Left very elusive and evasive voice message on my office line, and blocked her identity. I returned call, and she then said she was on a conference call and would return my call, but still gave me no indication of what she wanted. Then called me back and wanted to pitch some business development scheme.
