dead air but i'll assume it's the Google scam

This number called the office this afternoon. On the other end was a robocaller promoting some sort of investment opportunity where one could earn $1 million in 20 years with minimal fees. Needless to say, I hung up on this anonymous, too-good-to-be-true offer.

no one on the line

Called my cell phone.  When I didn't recognize the number, I hit the rd button (which sends it to voice mail).  They robocaller left a voice mail with some sort of message related to an investment scheme.  Didn't listen to hear the details - just deleted it and marked this number as spam.

This is the first time this has happened, but I received a message on Facebook from a random person saying to call this number. Of course I didn't, but this is getting ridiculous.
