Everyday, I am receiving such calls, not only this number but others with an out of state prefix. Most times no one will be on the other end when answered. I no longer answer a call unless the number and name in my contacts list. If they haven't left a message I block the number.
The numbers look like AU numbers but somehow they are disguising the real callers number and overseas prefix. There must be a way for the phone services to identify and block them before they reach us.

I received a scam hoax phone call from dodgy Credit Corp (02) 6310 9437 on my unlisted phone number and they did not leave a message and when you ring the number back they will not disclose their organisations name so I blocked the number. The Australian Competition & Consumer Commission (ACCC) produces a Debt collection guideline for collectors & creditors https://www.accc.gov.au/publications/debt-collection-guideline-for-coll… Unnecessary or unduly frequent contacts may amount to undue harassment of a debtor. The ACCC recommends that you do not contact a debtor more than three times per week, or 10 times per month at most.

I have also received harassing phone calls from Credit Corp from the following phone numbers:
