02 8550 3391 (0285503391): Contributors report impersonation calls falsely claiming to be from CBA, Telstra, and financial institutions requesting transaction authorisation and personal details.
Impersonation Scam Reports for 02 8550 3391
Five contributors have reported suspicious activity from 02 8550 3391, also written as 0285503391. The overwhelming pattern involves callers falsely claiming affiliation with major Australian banks and telecommunications providers. Four of the five reports involve deliberate impersonation tactics, with callers pretending to represent CBA, Telstra, or generic financial institutions to extract sensitive information or authorisation for unauthorised transactions.
The most common tactic reported is impersonation, appearing in three separate instances. Contributors describe callers who identify themselves as representatives from Telstra's technical department or CBA fraud teams, then request transaction authorisation, personal details, or verification of account information. These calls demonstrate characteristics consistent with organised scam operations, including call centre background noise, initial delays before the person speaks, and immediate disconnection when questioned.
What Callers from 02 8550 3391 Claim
One contributor received a call from 02 8550 3391 where the caller claimed to be addressing an $1800 CBA transaction, despite the recipient having no CBA account. When the contributor called back, they received only a generic response, providing no legitimate callback mechanism or verification.
Multiple contributors report Telstra impersonation attempts from this number. One caller claimed the recipient's internet line was being changed from private to public, suggesting personal details were compromised and requiring immediate action. Another caller identified as being from Telstra's technical department with an audible call centre background. Both contributors who encountered Telstra impersonators reported the callers hung up immediately when challenged with verification questions.
A robocall variant from 02 8550 3391 delivered a recorded message requesting transaction authorisation without identifying a legitimate organisation. Another report described a call claiming the recipient had made a purchase on eBay, though this was identified as spam rather than a scam attempt.
Report Patterns and Timing
The reports span nearly two years, with the earliest impersonation scam reported in March 2024 and the most recent in January 2026. Three of the five reports involve answered calls where contributors directly interacted with the caller, suggesting 02 8550 3391 is actively dialling and connecting with recipients. Notably, both Telstra impersonation calls occurred on the same date in March 2024, potentially indicating a coordinated campaign or batch dialling activity.
The call centre background noise reported by two contributors suggests this number may be part of a larger organised scam operation. The characteristic pattern of immediate disconnection when recipients attempt verification is consistent with call filtering or manual hang-up protocols used by scammers to avoid extended tracing.

Recorded message wanting a transaction authorisation. Scam.
Spam call saying I had made a purchase on eBay.
I have just received a call from this number; when I answered there was an initial delay before the person spoke. The person claimed to be from Telstra regarding my internet line going from private to public advising that my private details may be compromised.
When I told him I was going to call Telstra to confirm if this was the case, he hung up.
I got a call from this number, and it was someone claiming to be from Telstra's technical department. The background noise of a call centre was very audible. When I started asking questions, they hung up.

WRITE A REVIEWFrequently Asked Questions
What should I do if 02 8550 3391 calls claiming my Telstra line is compromised?
Hang up immediately. Contributors report 0285503391 callers use this urgency tactic to pressure quick action. Never follow a caller's instructions to disconnect services or provide details. Instead, contact Telstra directly using the number on your bill or their official website to verify any claims.
Why did the caller from 02 8550 3391 hang up when I asked for verification?
Multiple contributors experienced this exact behaviour with 0285503391 - callers disconnect as soon as they're questioned or asked to verify their identity. This is a classic scam indicator. Legitimate organisations support verification requests; scammers avoid them.
I received a robocall from 02 8550 3391 asking me to authorise a transaction. What does this mean?
One contributor reported a recorded message from this number requesting transaction authorisation without identifying a legitimate organisation. This is a phishing attempt. Do not provide any authorisation, and do not call back the number. Report it to Scamwatch at scamwatch.gov.au.
How did the caller from 0285503391 know details about my accounts?
The caller claiming an $1800 CBA transaction may have obtained information from a data breach or purchased compiled contact lists. The Telstra impersonator's knowledge of your internet service is a common social engineering tactic. Never assume the caller's knowledge proves legitimacy - always verify independently.
Should I call back 02 8550 3391 to verify if it's legitimate?
No. One contributor called back 0285503391 and received only a generic response with no legitimate callback mechanism. Calling back confirms your number is active and may result in further scam attempts. Instead, independently contact the organisation using official details from your statements or their verified website.
What's the difference between the CBA and Telstra scams from this number?
02 8550 3391 is being used for multiple impersonation scams. The CBA variant involved a false transaction claim; the Telstra variants claimed internet security issues. Both used the same tactic: create urgency, request personal details or authorisation, and hang up when questioned. The number appears to be a tool for organised scammers testing multiple impersonation angles.
