Received a scam/phishing SMS today from +***** stating that my account was overdue $10.24. It didn't say if it was a mobile or internet account.
This is pretty sneaky. I have reported to the Optus abuse mailbox and to the ACCC scam site, but thought I should post here for users.
That's part of this Optus phishing nest:
Of which Optus is only currently aware of one so far by the looks of it (as only one is being actively blocked).
They all ask for your Optus My Account login details as well as credit card details. They're even nice enough to give you a fake receipt after you've made the payment.
