calls my house seven times a day.  gets really annoying.

keeps calling but no one talks when I answer and they don't/won't leave a message on machine. They call several times a day and hang up after I say "hello" twice. Real pain in the neck! Call back to this number is always busy.

Calls repeatedly.  Leaves no message on machine or with anyone else when they are not me.  Attempts to return call results in constant busy signal.
