NAB Impersonation Scam Reports for 03 9322 6426

Two contributors have reported scam activity from 03 9322 6426 (also written as 0393226426) involving impersonation of NAB (National Australia Bank). The scam specifically targets recipients with false claims about Commonwealth Mastercard transactions and escalates to aggressive threats when questioned.

One contributor received a call from 0393226426 claiming to represent NAB regarding an unauthorised Commonwealth Mastercard transaction. When the recipient questioned the caller and stated they don't hold a Commonwealth Mastercard account, the caller became aggressive rather than verifying details or transferring to a legitimate department. Another contributor received a deceptive email appearing to originate from NAB but linked to 03 9322 6426, confirming this number is actively used in coordinated scam attempts across multiple channels.

What Callers from 03 9322 6426 Claim

The caller from 03 9322 6426 falsely claimed to be contacting about an unauthorised Commonwealth Mastercard transaction requiring immediate verification. When challenged, the caller became hostile rather than following standard bank security protocols.

Contributors report that when they attempted to verify the call by ringing back 03 9322 6426, they reached a voicemail claiming to be the NAB customer ID line. This is a known scam tactic - creating a false callback number that appears legitimate to deceive callers into thinking they've successfully reached their bank. The combination of impersonation, false transaction claims, and aggressive behaviour when questioned indicates a coordinated fraud operation targeting NAB customers and non-customers alike.

Report Patterns and Timing

Both reports about 0393226426 arrived within four days of each other in early December, suggesting an active campaign. One contributor encountered the scam via phone call (call answered channel), while another received the initial contact via email, indicating the scammers use multiple communication channels to reach targets. The aggressive escalation when questioned suggests the scammers are not equipped to handle legitimate security questions - a red flag that distinguishes this from genuine bank calls.
