Beware of Impersonation Scams

Government officials will NEVER do these things over a phone call:1. Ask you to transfer money;2. Ask you to disclose bank log-in details;3. Ask you to install mobile apps from unofficial app stores;4. Transfer your call to Police.

Call the 24/7 ScamShield Helpline at 1799 if you are unsure whether something is a scam. Learn more from our scam advisory.
