Caller: Recorded message

This call showed as coming from Parramatta, NSW. When I answered a recorded female voice told me that she was from Amazon and that my account had automatically been debited $99.99. I did not respond, simply hung up, as it was a scam. I had received an identical call about an hour earlier, also from Parramatta, but using a different number. Again I simply hung up without responding. Someone is obviously using a block of numbers from the Parramatta area for scamming purposes.
