(02) 4326 0659 rang, I answered, they hung up. Probably just checking if the number is still working. Might introduce them to a whistle next time they call

I called back number (02) 4326 0659 reached voice mail but did not say from what company.

This is a company called CB wealth. It's a scam telling you that you've won a financial health pass & a tablet. I was sitting with a friend when I got the call, they called her phone 10 minutes later with the same spiel..
It also calls on (02) 4326 0804
