Calls and says: "Hello" into my voice mail. Dude, nobody's home!

Called a while ago i missed it, they didnt talk in the message. Called my cell phone again today and said my name and the name of my family members!
i called it back and all it said is if i kno my parties extension to dial it now.

I called them back. Some place called Network Refinance. Telemarketers I'm sure.

Called yesterday when I was not at home. Kept saying "Hello" into my answering machine.
