I had thesame type of call last night however they asked for me by name but would not divulge what it was about therefore the wife who answered would not let them speak to me.  They aslo said they would call later and hung up.

A caller named "Leah" asked for my wife by name and was insistent on speaking with her.  She would not discuss her business with me or put my wife on the phone, she abruptly said she would call back later and hung up
