Same here, they tried to make it sound official. Hung up on callback

Missed the call from this number. Half an hour later received call from this number. An automated message about the Federal Government's (Australia) insulation rebate. Press 1 if you're a homeowner, 2 if you're renting. HUNG UP on call ...

This call went to our answer machine that recorded their pretaped message. Said Press 1 if you're a homeowner, 2 if you're renting ... 4 to remove yourself from this call list. We are a silent unlisted number and on the "Do not call Register" This had better no be the government abusing their power to bypass the silent wall we hide behind. Rang the number back and they hung up on me. I want to report these bastards.
