I called back the number 0404 183 615 and the guy on the other line did not mention the company name

Rude and constantly rings the business landline have asked him not to call numerous times - scam

Just wants donations. Will call back repeatedly. Block the number.

This is a scam
Hang up on this aggressive a**hole

I called the number back due to the male person on the other end just hangs up when the person he asks for is not in the office.
He is a very angry man saying he is collecting money/donations for the defense force
remembrance day when i asked him not to just hang up on people he went off on a rampage
