Caller: (03) 7048 0413

Rang answered call, caller hanged up less than 2 minutes later called again could not understand caller told them to stop ringing me then I hanged up. Block the number.

Got a call from these morons just now, I answered and got no response then they hung up. So I called them back, number goes to an automated system that tells you that "your call is being transferred" but it just rings a few times and disconnects.
