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

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

I called back number (07) 3144 6377 reached voice mail but did not say from what company.

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.

I rang back the number (07) 3144 6377 once but got disconnected
