Call centre, hung up on answer

Phone doesn't even ring and keeps generating missed call notifications without leaving a message.

I am having the same thing with this spam number. Calls every few days. If i answer there is no one on the end. . . .Blocked it now

Someone on the other end, did not say anything.
I hung up after saying hello three times.
When I rang the number back , it said it was disconnected.

Missed calls x2 no message

Called today hung up when I answered, tried calling back suddenly disconnected. I contacted Optus ( Message said the Optus number you called is disconnected) to ask them how they do this ? all optus could say was to block the call could not / would not tell me how this works.

My mum has gotten a few calls from this number when she answers there’s nobody on the line.
When she’s tried calling back it says that the number is disconnected.

Caller: SPAM

I called back from my mobile and landline and number disconnected - they call at least 4 x day! Extremely annoying and SPAM

Yep, have had this number a few times & I don't answer calls without an ID I recognize. Now blocked & simply up's my caution about answering anything random

She called, I said hello then she mentioned my name and said she is not from a particular company and went on about to save with a different electrical company. I said I don’t trust this number and hung ip

Caller: 0421 056 887

Can almost set the clock by when this number calls . I don't answer unless there's an ID .

This number tried to reach me multiple times throughout the day without leaving any voice message. Luckily, my phone settings automatically detect spam calls and reject them. After googling the number, this forum further confirmed that this was indeed a spam.

100% SPAM
