Potentially Credit Corp. They also ring from other numbers very similar. Scammers who want you to identify yourself to them, but yet who do you know is on the other end of the phone and where your details and going. Never verify your details to these harrassers!

They called my mobile phone. However, they didn’t leave a message.
Reading OP they are credit corp. SCAMMERS
DO NOT ANSWER OR CALL THEM BACK
They’re illegal.

Report this phone number (07) 5512 2453 from Credit Corp to the ACCC Scamwatch https://www.scamwatch.gov.au/report-a-scam and AFCA https://www.afca.org.au/ I received the scam hoax phone call from dodgy Credit Corp (07) 5512 2453 on my unlisted private 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 and reported it to the ACCC Scamwatch. The last time I had credit or a debt was 20 years ago. 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 the dodgy Credit Corp from the following phone numbers:

Caller: Weird lady

Answered the phone, a weird kinda drunk sounding lady asking who I was, when asked who she was, she did not want to provide any details, so I simply hung up on this lunatic woman.

Caller: A weirdo

I answered hello. I heard a male breath and gulp ( kind of a sound ) they stayed on the phone then hung up.

Caller: Scam

This is a scam call, they ring via different numbers across Australia claiming to be debt collectors to sales. They are scammers. Do not answer. register with donotcall.gov.au.

I called back the number (07) 5512 2453 and the lady on the other line did not mention the company name
