this number has called me on mobile, so I rang off landline and it says Optus regrets but the number you have called has been disconnected

Caller: A man claiming to be a Telstra Technitian

He wanted me to press ctrlR on my computer, because my internet has been hacked.

I put the phone down and walked away, went back a little later and he was still on the line, so I rang bells into the phone. I wonder if he got the message 🙂

Caller: Telstra

Multiple calls day and night. No message left. Answered twice and told them politely not to call again. Tech support to help me with my computer and internet issues.

No response on answering. A scammer for sure.

Strange caller, no answer but then the female voice recording said GOOD-BYE. I am worried they have recorded my "hello" for something. DONT ANSWER NUMBERS YOU DONT KNOW THEY WILL FIND ANOTHER WAY TO CONTACT YOU IF THESE ARE LEGITIMATE CALLS.

no response when answered

Caller: Allan from telstra apparently

Has called numerous times just hung up coz ive said nothing or not even answered but today i said hello and questioned allan from telstra told him ill call him back which i did and number is disconnected and he hung up now wait and see if he calls today

this number has called my phone multiple times.
when i call back it is disconnected

Rang three times today left no message. Third time I picked up. Usual delay in responding to answer. Dead giveaway. Finally, in a thick foreign accent...
"Hello my name is Alan, I am from Telstra, about your computer. OK?"
Scammer as expected.
My response... OK. No thanks. Goodbye.

Called 3 times today. Hangs up after about 2 seconds.

Has rang a number of times today. I am not answering because it isn't a number I know and have had
far too many scam calls.

Called back, number could not be connected.
