One contributor identified an accent inconsistency, with the caller claiming to be located in Melbourne while speaking with an overseas accent, a common indicator of offshore call centre operations.

WRITE A REVIEWFrequently Asked Questions
Why did the caller from 02 9129 8820 know my name?
Contributors reporting calls from 0291298820 noted that callers addressed them by name, suggesting the scammers may have obtained personal information from data breaches or public databases. Legitimate Telstra support also uses name verification, which makes these scams more convincing. Never assume a caller is legitimate just because they know your name - always hang up and contact Telstra directly using the official number on your bill or their website.
What does a 10-second silence before the caller speaks indicate about 02 9129 8820?
One contributor from 0291298820 reported a 10-second silence before the caller spoke, which is a characteristic feature of robocall systems. These automated systems dial multiple numbers simultaneously and connect to a live agent only when someone answers. This delay confirms the call originated from a large-scale scam operation rather than a legitimate customer service centre calling you directly.
Should I call back if I miss a call from 02 9129 8820?
No, do not call back 0291298820. One contributor who tried to return a missed call from this number received a "service difficulties" message, which is typical of spoofed numbers. Scammers use spoofed numbers precisely to prevent callbacks. If you missed a call claiming to be from Telstra, contact Telstra directly using 13 2200 or the number on your bill.
How can I verify if a call from 02 9129 8820 claiming to be from Telstra is real?
Legitimate Telstra support will never call you unsolicited claiming your IP address has suspicious activity. If you receive such a call from 02 9129 8820 or any number, hang up and call Telstra directly on 13 2200 or visit telstra.com.au. Never use numbers or contact methods provided by the caller - scammers may provide fake "Telstra" numbers that connect back to their operation.
Is 02 9129 8820 actually operated by Telstra or the Australian Cyber Security Centre?
No. The number 0291298820 is allocated to a local service provider in NSW but is being used by scammers to impersonate Telstra and the Australian Cyber Security Centre. The overseas accent noted by contributors and the technical impersonation tactics confirm this is a fraudulent operation. Neither Telstra nor the Australian Cyber Security Centre operate through this number.
What should I do if I already provided information to a caller from 02 9129 8820?
If you shared personal information, passwords, or banking details with 0291298820, act immediately: change your passwords, monitor your bank and credit card accounts for unauthorised transactions, consider placing a fraud alert with your bank, and report the incident to Scamwatch (scamwatch.gov.au) and ACMA (acma.gov.au). Contact Telstra on 13 2200 to confirm your account hasn't been compromised.
