I called back number (02) 6145 0120 rang once then gets disconnected automatically.

Yes I got sucked in and bought the Apple I Tunes costing $300.00 . I am usually a wake up to these scum but they sounded so genuine and they gave me the number and asked me to call back. They said I have a back payment owing on my pension and as I haven't been getting a regular amount I believed them!!!!

This number is a scam. People pretending to be from Centrelink, and they aren't. They are threatening and abusive. They start out saying that you are owed money, but it quickly turns to a warrant being issued for your arrest.
