I called back the number (02) 9159 2559 but the phone just kept ringing

Caller: Victor from Sydney

Victor (foreign) after the niceties of 'how are you today' (twice) was slow to explain what the call was about. He finally said the company was Kalkine, I asked for the third time what was the phone call about and his reply was 'F*** you' and then he hung up. I have blocked this number.

Rings and hangs up. Robo Caller to scam you!

they called but hang up before I could answer.

Scam

I picked up and no-one answered, then disconnected. 20 minutes later, get a call from blocked number - some guy trying to get me into stock tips or finances? I told him my number was on the Do Not Call list and I would be reporting him and his company and said I wanted his number etc. He said he would call me back later - I told him not to and hung up. TOTAL SCAM!

As others have said, supposedly from Kalkine, offering free sample stock tip reports.

Caller: I don’t know

Yep some Indian dude wanting me to invest in stocks and saying he can arrange finance for me to be able to do so

An indian person claiming to be from Kalkine stock market. a little bit of research and this number isn't associated with the actual Kalkine company. total scam
