WRITE A REVIEWFrequently Asked Questions
Should I answer if 04 2398 9440 calls me?
No. If 0423989440 is an unknown number, let it go to voicemail. If the caller hangs up when you answer (as reported by one contributor), there is no legitimate reason to engage further. Do not return the call.
Why might someone call 6 times in a row and hang up when answered?
This pattern is often used by callback scammers to verify that a number is active and answers calls. Once they confirm this, they may later call with a scam pitch. Blocking 04 2398 9440 immediately after this behaviour prevents further contact.
Is 04 2398 9440 definitely a scam?
One report describes suspicious behaviour (repeated calls and a hang-up), but without additional details, we cannot confirm the caller's intent. It could be a technical fault, harassment, or a scam probe. The safest approach is to block 0423989440 and not engage.
What should I do if 04 2398 9440 keeps calling after I block it?
If the number continues calling from 04 2398 9440 via different methods or appears to be using a spoofed number, report it to the ACMA at acma.gov.au. This behaviour may constitute harassment or a breach of telecommunications rules.
Can I report 0423989440 to the police?
If calls from 04 2398 9440 are persistent and causing distress or fear, you can report harassment to local police. Start by reporting to the ACMA and Reverseau to establish a pattern, then contact police if the behaviour escalates.
Why does 04 2398 9440 show as an Optus mobile number?
The number is registered to Optus mobile, but this does not mean the actual caller owns that account legitimately. Phone numbers can be spoofed, compromised, or misused by scammers. Always verify the caller's identity through independent channels rather than trusting the displayed number.
