got a call asked for me then they hung up

got a call last week and again this morn.  then hung up.

Keep calling and either:

A) Disconnect when I answer - autodialer, or
B) Ask for my wife, and when I ask who's calling, they hang up on me.

Calling multiple times a day.

They did the exact same thing to me!

They asked for my wife. I said "May I ask who is calling?" and they hung up.
