An Australian woman claiming to be calling from "Premium", wanting to let me know about a government tax incentive. She insisted she wasn't selling anything, but really didn't want to take "no" for an answer.

i have been getting heaps of calls from different numbers. I answer, they hang up. I rang it back straight away, and it says it's disconnected

I got two missed calls from this number and when I called it I got the following response: THE NUMBER YOU HAVE CALLED IS NOT CONNECTED. PLEASE CHECK THE NUMBER BEFORE CALLING AGAIN??????
