Tried to call back - unable to connect

Rang my number and as it wasn't on my contact list, I didn't answer it. They didn't leave a message. Assuming it was one of many scam calls i get on a regular basis.

Caller: Peter (Scammer)

Says they are from "Telstra" IP security and address has been compromised.
Told him that "if" they looked after my service, and they don't, they would be able to fix this without my intervention.
Asked him for a number I can call his team back on and he hung up :D

Some foreign dropkick talking about some transaction, I told him to get a proper job and to stop trying to scam people. He then mentioned repeatedly that I should suck his cock, I told him that he should stick with f*cking his mother, then he hung up.

Told me my phone number was being used by someone is America to set up child porn accounts on Twitter and Tinder, I hung up before hearing what else she has to say. Indian women clearly reading off a script

Caller: Claim to be from NBN

Scam call from "Telstra", but when I informed them the phone they called is a government issued work phone that not many people have or need to know the number, they promptly hung up.

Scammer . . . tried to call back but get no where, voicemail said they were from Telstra and needed to speak to me concerning my account . . . I am not even with Telstra!
