Telstra Impersonation Reports for 03 9003 4510

One contributor has reported receiving a call from 03 9003 4510 (also written as 0390034510) where the caller claimed to be from Telstra. When the recipient stated they were not a Telstra customer, the caller immediately hung up. This pattern of abandoning the call upon verification request is a common tactic used by impersonators who lack legitimate account information.

A second report about 0390034510 identifies this number as part of a persistent spam pattern. The contributor notes this interstate landline has been calling at regular intervals over several years, always clustering around the same afternoon timeframe, with the frequency now reduced to approximately once every 4-5 weeks.

What Callers from 03 9003 4510 Do

The defining behaviour reported for 03 9003 4510 is the immediate disconnection when questioned. Rather than attempting to provide account details or follow through with a pitch, the caller simply hangs up once confronted about their claimed Telstra affiliation. This suggests the caller has no legitimate reason to contact the recipient and is likely working from a generic calling list without customer-specific information.

Contributors have observed that calls from 0390034510 follow a predictable timing pattern, arriving during business hours in the afternoon. This consistency suggests an automated or semi-automated calling operation rather than a one-off scammer.

Report Patterns and Timing

The two reports about 03 9003 4510 show distinct patterns. The impersonation attempt was answered and immediately revealed as fraudulent through simple verification. The second contributor's experience spans years, indicating this number has been used repeatedly for spam operations. Notably, the long-term reporter has successfully reduced contact frequency by never acknowledging the calls, disabling voicemail, and rejecting the call rather than cancelling it. This absence of any interaction signal appears to have dramatically reduced the calling rate over time.

What to Do If You Receive a Call from 03 9003 4510

If 03 9003 4510 calls you:

• Do not: Confirm your name, account details, or customer status. Do not provide any response that indicates someone is monitoring the line
• Do: Let the call go to voicemail, or reject it silently without cancelling. Never pick up or engage with the caller
• Do: Disable voicemail if you receive repeated calls, as an active voicemail service signals an active line to the caller
• Do: Block the number on your phone to prevent future contact attempts
• Do: If you have a Telstra account, verify any legitimate issues directly by calling Telstra's official customer service number from your bill or the Telstra website, never by calling back
