I get called every day, always from a different number, different state, and they never leave a message. This was the one that called today. I answered "Hello?" He responded, "Hello?" I said, "Hello" again, then it was a little garbled, then I heard, "...is this Miss H****?" They knew my name. I replied, "Who is this?" and they hung up. I tried calling back and heard some nonsense prerecorded message about that number being unavailable at this time. I used to think it was debt collectors. I'm debt-free now and they still call.
