I keep getting this number calling. He asks for my husband. When I say he is at work, he hangs up. When I ask to take a message, he hangs up. When we call the number back, is is not in service.

Same thing happens to me. Twice now.

They didn't leave a message

Same thing here.  This number has called every day for the last month and today finally some guy asked for my husband and when I asked who was calling he hung up.  I have tried calling number back and I get a message that it's not in service.  Weird?!?!

This caller is really getting on my nerves. He calls every day, asks for my father, and then immediately hangs up. Get a life, buddy.
