Definitely a scam call. They actually rang my 4G/LTE modem number, needless to say no-one answered. It's a mobile number only supposed known to Telstra. How they hack these numbers is beyond me. Any case just hang up, or better still get one of those loud siren aerosol horns and blast them down the line.

Definitely a snap caller

Caller: 0420 040 298

Called me and after a long pause a man spoke and told me he was from ‘insurance’ and that I had been in an accident. Knew my name but didn’t know what insurance company he worked for. I had not been in an accident. No doubt this is a scam as the number comes up to several different nuisance/spam calls.

Caller said that they were from Telstra and that there was malicious hacking tools downloaded to my my computer. Told them that Testra isn't even my ISP but they insisted that they know becasue the Telstra network is Australia wide. I didn't let it go on much longer, just a "cheers" for letting my know, and I'll update my anti virus software and hung up.
