This caller keeps calling doesn’t leave a message and when I called the number back, I am told this number is not connected.

WARNING - This is a scammer. I have had this number blocked from my phone by Telstra. These mongrels called 34 times in a week and it is a "computer generated" call which means that they keep calling multiple times and completely clog up your Telstra 101 message bank. When you try to track them down the number is hidden until you dial "22" at which time you are charged to connect the call however Telstra then identifies the number as "(03) 9308 6441". The number is always "disconnected".

This is a scammer from overseas. I have reported the number to the Do Not Call Register and contacted Telstra to have this number permanently blocked from my phone.
They have called over 25 times, blocking up my Telstra Message Bank between October 30th and November 14th.
It will take about 24 hours but I should receive no more calls from these scammers.

Caller: (03) 9308 6441

This is a scam - they say they are from Telstra and your computer has been hacked - they want you to go to google - don't

I received 11 calls to my message bank from these clowns. When I called back I got the message that this number is not connected.
I reported this scammer to the "Do not call register complaints line".

Caller: Unsure

Keeps calling multiple times of the day

indian call centre. cant hear anything but noise. then says hes calling from telstra about my internet.. which is already with telstra... another scammer trying to get you to sign up to a dodgy deal at dinner time.

After a short period of silence on the calling end, I heard a high pitched beep and a computer voice said 'goodbye.'
