Calls then hangs up

After numerous calls last week, on today's call he would not tell me who he was or why he was calling, I had to be assertive and ask him not to call me again.

I had missed call from that number ‭(03) 9071 1887‬ sounds like scammers

Said they were an online trader would say who they were or that they would remove me from their call list unless I gave out my name address and date of birth

Rang twice leave no message

I have had 3 calls from a very similar number today, one including this exact number - no message left.

Caller: Accented Voice--Not understandable.

Accented Voice--Not understandable.

Answered with hello - hung up. Probably a scam criminal. So much for the Law in this country.
