"Know body"?

Oh, look it's the smart [***] grammar police. I'd be willing to bet you don't have very many friends.

Just filed a complaint on www.donotcall.gov regarding this phone number.

every day calls

I got a call from this number. They asked for Mr or Mrs with my last name. When I said. "Speaking..." they hung up. When I called back, I got a voice mailbox that is full....very strange. Anyone know what they are trying to achieve by these kinds of calls?
