Repeated hang up calls from this number

Pretending to be from an "IT department" and demanding I switch on my computer coz there is a "known"and "documented" issue with it. Wanted access.
Called them bluff and was abused and insulted for not cooperating with their demands.
Hung up as soon as the abuse began.

they didnt speak english at all

Repeated hangup on Answering

Repeated calls to home phone

Caller: He said his name, but I didn't catch it

Said he was from Telstra - but I know Telstra wouldn't be ringing me from a mobile - so I hung up

claiming to be from telstra technical department but calling from a substituted mobile number. definitely spam

Hang up call from this number.
