Someone from this number has called me twice today.  No message left.

The same thing is happening to me.

Called twice today. First time left no message. Second time hung up before the machine kicked in.

Received 3 calls from this number today and few calls on the 29th. No message left.

They have been calling for several days, never leaving a message. Tonight they called, back to back, over and over, 7 times, never letting it ring enough times to go to the machine. Pretty desperate... Figure it was legit, they would leave word.
