Hung up when I answered

Tried to get me to log in to my computer so they could access. The guys tone was getting very aggressive

Fake Telstra scam

Caller: Fake foreign callers using Australian numbers

(02) 4072 6664 is on the APP True Caller documented as
+96724072 6664 ( Yemen ) calling pretending to be Telstra - just BLoCK

It’s appalling that these Australian numbers are allowed to be purchased

Scammer for sure!

'Raymond Terrace' number - 'line busy' whenever I try to call back. Suspected scam caller.

Claimed to be a Telstra security ......

Scammer

Called and hung up. Number was unable to be called back

Scammer pretending to be from Telstra

Caller: I don't know

Called me but I didn't answer.

I was expecting a phone call, so called it back (I usually don't), but it came up as busy.

Checked here, and it is definitely an unwanted caller.

Caller: Scammer

I have TrueCaller on and my phone permanently on focus accept family in favourites so they can get through. It works for me.

Caller: claimed to be telstra

i hung up at that point as i have no services with telstra.

Caller: Telstra

Called me to talk to me about my telstra connection. I informed him I don't have Telstra and he said all other services use Telstra. I told him I work in CBD near Telstra offices and can he meet me in person at the Telstra offices to discuss. He said he would meet me at 4pm and I said "great, then you can try to rip me off and run your scam in person.." he hung up.

Caller: Supposedly Telstra technical department

Female with a thick Asian accent saying they were from the Telstra technical department.
The phone number was (02) 4072 6664 (a Sydney number) yet the woman told me that she was in Melbourne and read out the address of the Melbourne head office. When I questioned her about why she was in Melbourne yet the phone number was Sydney she hung up.

Caller: Who knows

I did not answer, and they hung up without leaving a message!
I have put the number into the contact on my phone called "Do Not Answer" for next time. :)

Caller: Telstra

Tried to give me some kind of booster for my router (I don’t have a router)

Claimed to be from Telstra saying I had malware in my router. Hung up when I started asking questions.

Caller: Claimed to NBN

Caller with Indian sub-continent accent attempted to gather details and asked me to run an NBN speed test.
Then asked me to enter run character string eventvwr such as a remote viewer application to take control of the computer (of course I didn't).
When asked for the call back number he hung up.
