These scam calls from numbers starting in (03) 9970 appear to be the relentless scammers from "Charity Prime" starting up again and using yet another series of numbers. I have never once answered their call - I don't answer calls from unknown numbers - and have blocked every range of numbers that they use, but nothing will make them give up. They've been reported to Scamwatch but keep re-emerging like a mutating virus.
Please do not answer calls from these or any other unfamiliar numbers.

It's started up again after Easter and I'm seriously over it - constant calls from pests who butt into my life and then hang up without leaving a message, obviously scammers. Please don't answer calls from unknown numbers of the plague will never end.
