Did the same thing to me as 'B', when I answered the call no one spoke and it just hung up. Almost seemed to be a robo dialer, have not figured out whom the owner is yet.
No message left. I gave my phone number to HARBOR FREIGHT STORE and the next day I started getting these calls. Won't do that again. I even asked them if they sell or give out your phone number. They said NO. What a LIE.
