called saying from Commonwealth Support Campaign. Claiming that we might be eligible for Government tax incentive / rebate. Have had similar calls in the past - basically looking to sell you investment property.

also helpful info to pay down mortgage sooner and set us up for retirement

They will be the winners, not you !

Insisted that they called not to sell anything, smells like a scam

I received the same call. She told me that it was only a survey . Wanted mine and my husbands mobile numbers to proceed. When I refused she couldn't understand why. She told me that by not giving her the mobile numbers that we would be missing out on a massive opportunity. When I asked for what the massive opportunity was, she refused to elaborate and went on to tell me that her supervisor would contact me at a later date.
I told her I can't wait...

Spam.
Time Wasters.
Just hang up on them.

yep call from same number 25/1/17 tried to call back says optus not in service

spam

Told the female caller I wasn't interested so she said it was for my benefit and I said I did not care if it was for my benefit. She dropped me loke a hot potato :-)

Received a call from this number today offering a tax incentive. When I said I wasn't interested he said "tough cheese" and hung up. Creep.
