A unsolicited callback from an unknown number, especially without revealing the business and with a non-local accent, often signals potential scam tactics. Scammers use this ploy to build false familiarity and extract personal details. Hang up immediately if details seem off—don't engage. Block the number via your phone settings to stop repeats. Report suspicious calls to authorities like the ACCC in Australia for tracking. Enable caller ID apps for better screening, and never share info over unsolicited calls. Staying cautious protects against identity theft or financial fraud.
They say they're returning my call (though I never dialed), refuse to reveal their purpose, and speak without an Aussie accent.
