This call showed as coming from Bakery Hill, Victoria. I had missed the call so it diverted to my message bank, but the caller left no message. When I called the number back a recorded message told me that the number was not connected, so I strongly suspect it was someone setting up a scam. I had a call from the same district (and a very similar number) the previous day, a recorded scam message telling me that Amazon was taking money from my account. Obviously the scammers are using hi-jacked numbers.
