Asked for spouse by first name as if he knew him personally

We have been getting these calls in the past and before today they were the same as Bobby's comment above (or below). The caller always asked for my wife by name. I recognised the voice and number and told the guy to stop calling and to take our number out of their database. The next time I answered a call from him, yes the same guy, I got mad and cursed him up and down for not taking our number out their database. He said, "How do you know it was me?" That sent the blood pressure even higher. Anyway today when we got the call, they hung up when I answered.  But I bet we haven't heard the last from them.

Yesterday the number 709-757-1382 was on our call display but no message left - the number is unlisted. When another call came in this morning, I didn't answer. There was a short delay on the line when my machine picked up and the caller did not realise that the call had gone to a machine - he asked for my spouse by his first name a few times and then hung up.
Our number is publically listed in my husband's name - I guess this is how they go about it??

I called the number back - it was busy the first few times I tried. When my call did go though, I heard a digital answering machine message. They did not identify themselves, the female digital voice said "we are not available at this time...if you would like to leave a msg press 1....be sure you leave your name and phone number......".

When ever my wife answers this call they ask for me, if I answer they hang up.  I would like to know who it is.

Yes I understand what you are saying about these calls. We too have been receiving the same kind of calls from this number. They are now calling and just hanging up when we answer. Weird for sure. I hope that this is stopped soon because it's driving me bananas.
