Showed up as a missed call on my work phone. Caller didn't leave a message.

I got a hangup call on my house phone, which I only use for Internet.  I called them from another phone and the woman didn't even answer the phone with the name of the company, just "can I speak to so-and-so?". She refused to tell me the name of the company or the full name of the person they were looking for (which wasn't me) and she hung up on me.  Obviously more bottom-feeding lowlife junk debt scam artists.

5-3-12 call today at 8:23,and againat10:29 so for just hang up.
