Caller: Suspected scammer

Received a call on mobile from above number; I didn't answer because I didn't recognize the number. Only rang a few times and caller hung up, so I suspect it's a scam of some sort; if caller was legit they'd leave a message. Blocked the number. There are so many of these fks around at present; call is probably from overseas 'hiding behind' an Australian mobile number. Sie konnen mir am Arschlecken!
