Screen incoming calls from unknown numbers before picking up to avoid surprises. This one claimed to offer Optus discounts but used personal details like your name despite you not being a customer—classic scam tactic to build false trust. Hang up immediately if they mention companies you're not affiliated with, and never share more info. Report the number to Optus and your phone carrier to help block it. Enable spam filters on your device for added protection, and consider apps that identify suspicious callers. Staying cautious prevents identity theft risks from these persistent nuisances.
They claimed to offer a discount on my Optus account even though I’m not an Optus customer, yet they knew my name.
