Nuisance call. Guy kept saying "hello" to voicemail.

Calls constantly, either hangs up or tries to scam.

Have called me 8 times
Leaves no message
Based on the other comments here I am blocking this number

Claims to be Telstra and hangs up when you don't respond in the way they want you to. Spamming call centre as there is the delay when you answer. This also may have been the number that states your internet connection has been taken over by hackers but hey, they will fix it. They will request control of your of your computer to fix it and scam you!

They must call 10 times a week but never leave a message. DON"T ANSWER or BLOCK

Male person said he was from Telstra and that a Mr Johnston is using my landline number.

Caller: Have then on block

Already have them on my blocked list previously. So is a spammer.

I called back the number (03) 8672 2951 but was routed automatically to an ivr
