They just called me, too.  There's a pause then an auto-recording, "please hold for an important call" and then somone comes on live, but at that point I'm already hanging up.  Don't know who this is yet.

Has called a few times - woke me up this morning - but never leaves a message. Beyond annoying,

The last couple of days they have called but never leave a message.

Call all the time and never leaves a message

Calling me 6 or 8 times a day -- leaves no message
