The Australian Communications and Media Authority (ACMA) has today registered new rules that require telcos to detect, trace and block scam calls. The Reducing Scam Calls Code, developed by the telco industry, was a direct recommendation of the ACMA’s Combating Scams Action Plan. This number 0422 764 493 is claiming to be from ComBank Cyber Security ... Optus needs to track, trace and block this scam number as they are required to do by the ACMA.

Caller: Scammer from Optus number

This number 0422 764 493 is claiming to be from CommBank Cyber Security. I don't have any accounts with CommBank. It is an Optus number and Optus is refusing to fix it by blocking service as they are required to do.
