Claimed to be ringing from Sunshine Solar. But 0033 1899 doesn't even look like a real number and I can't find any Australian companies called Sunshine Solar.

Just had call from this number , no answer , just hung upon me

Some Indian sounding voice about Solar Energy. Told me we all should be saving energy, agreed and told caller he should be saving his energy and mine by not wasting his time and mine, I get similar calls all the time. Obviously a fake company with a spoofed caller ID, some attempted scam. Insisted on keep talking, so just hung up on him.

This clown (Logan) argued with me that he was not a telemarketer but calling as part of a government initiative (though I've had a dozen calls from that same number where nobody is on the line). I told him I'd google his number to prove he was a telemarketer, so he refused to give me his number and told me I was wasting his time. So I went to my call log, googled the number and started quoting him comments from this site and he hung up on me. I called him back and got the message "Optus advises the number you dialed is incomplete".

Had a call, no message and just hung up on us.

Greenfields Solar today.

Silence and then hangs up.
Don't pick up if you see (03) 0035 1988 on your caller ID.

Same scam artist as the charity one.

Just had 2 calls in a row from this number, no answer, just hung up on me

Not smart. Called and asked for our business manager after hours!
Our cleaner answer the phone.
