I called back after hours and got a recorded message from Credit Corp.

I received a scam hoax phone call from (07) 3144 6377 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.

Lion Finance or Credit Corp.
Third party interlopers. Do not answer.
Do not give them any information.
