Who called from 2032129964

Got a call at 6:32pm EDT 3/26/13.  Call did not connect immediately, and call dropped.  I called back, it is a staffing company that thinks I expressed interest in their services online. As far as I can recall, I did no such thing.

Just received a missed call on my cell.  Only people that know my cell are close friends and family. How did they get my number?

A call, no sound, but I looked it up and saw that others report it as a nuisance advertiser of some sort.

Didn't leave a message

calling back, i was immediately informed by a voice robot that i had been called by WN Positions regarding "job opportunities".  I'm on the Do not call list so I believe this is illegal.

(Call Type I left as "Unknown" because there's no Other, Commercial, etc. choices.)
