Asked if I was the owner and wanted to advertise my business. He mentioned the police but I didn't catch all of it.
He was quick to hang up when I said I don't give out my details over the phone.
Sounds like a scam.

Called saying something about the ATO and my partners company name, he did not say anything to them, they said they will call back, I will block the number now.

Called and asked about my company, I pretended not to know about it so they hung up, definitely after some money. I rang the number back and they don't pick up, rude bastards

Wanted donations for AFPA. Shot and injured police for a football tournament.
Definitely a scam.
