Dead line when picked up, hangs up shortly after

Have blocked this number. But they keep ringing. When will they give up. If I don't answer why keep trying. Yelling at them. Blowing a whistle and blocking the number doesn't stop them. What else are we meant to do.

No message left; several calls

Called and didn't leave a message. Based on everyone's comments, have blocked number.

Caller: SA Energy/ Energy SA

Supposedly selling solar panels and batteries.
They gave me a web address which seemed legitimate so I called the contact number there to see if they were making the unsolicited calls. Unfortunately the man there did not know if they made such calls and couldn't confirm if the 74777981 call came from them or not.
Lastly my number is on the do not call register, so I reported the call to them.

Caller: ?Energy SA

Energy SA?? Selling solar. Connection was terrible and sounded dim and distant. Male voice - calling re federal government solar rebate scheme. Dont know where they got my name- I'm not a customer nor have i enquired about solar. I get constant calls from them. Most times dont pick up. Told them my roof is old and not able to support solar and not to call again.

Called 3 times in one day. First time I missed the call, second time answered and they said they were calling about a solar rebate. Told them I don’t have solar and hung up. They called back immediately, sounded frustrated and I told them not to call my effing number again and blocked.

Regular caller. Identified by Smart Phone as 'Suspected Spam'. Blocked but still rings through.

Did not answer
No voicemail left
Assume scam

Caller: (08) 7477 7981

I missed call but they had set up automatic return call. So it was a returned call outside of my control to be met with nothing.
My thoughts it’s scammers to see if number is active.
Await to see what they will do next.

they tried several times, dead line and no one there, so number blocked, we will see but the world just has another scumbag

They’re still going. 2 calls in 2 days to a mobile. The first I didn’t answer and answered it today but there was nobody there.

Caller: Energy SA??

Energy SA - asked for me by name - calling re federal govt solar rebate scheme. I'm not Energy SA customer. Claimed got my name & number from census. (not publicly available information). pushy salesperson - unsolicited call. Spam. Blocked

Have had quite a few calls from this number - silence when I answer - hope for luck when I block the numbet

Have been contacted at the same time over several days. Tried to call number but the line was 'busy'. Have now blocked the number

Called me twice. I said hello but there was silence save for an odd roaring noise like vehicles in a tunnel on the line. Blocked number after this

Caller: MoveIt

The call is from MoveIt - a removalist company. We enquired 3 years ago, told them no and went with another company - yet they still call. At least weekly

Keep calling but won’t leave message. When answered once, long delay so hung up. Ph warned as scam

Came up on my phone as "Spam call" so I just declined it. Can't be bothered with these idiots. Why do they always call at dinner time??
