Caller: Scammer pretending to be centrelink

Recorded message saying they had tried to contact me by email, phone, and letter about my "application". They were trying to give me more money but as I hadn't given them all the info they had referred my case to Canberra (der!) and I should call them with the reference number 080456. Yeah right! Same "reference number" as all the other Centrelink scams, just using a different displayed phone number now.
