According to a Facebook post I found after searching for the number, the guy on the other line is conducting a survey on mining, and swears at you if you've given the wrong answers?! I don't know myself, I never answered, but called the number back and it said some market research company.

A lady IVON called offering me a web design , when I said I’m no interesting she processed to tell me that I was a f*cking stupid .. and hang up , hope this number get blocked …

Caller: Curry muncher

It’s another web site company

I called back the number 0488 823 539 and reached vm that said I reached EMRS

Did not leave a message, apparently someone taking a survey on mining issues, and if you give the wrong answers they swear at you 🤷‍♀️ (according to a post on Facebook I found after searching the number)

Hung up when I answered

Caller: some survey company

Well, that was strange, I normally respond to survey questions on the phone, as I do not mind giving my opinion the bloke that phoned me did not like the answer I gave about the Oil and Gas industry and proceeded to swear at me. Yes, I heard you mate, and as a result, I hope you lose your job. It seems you were not interested in honest responses. even though I chose to give it a middle of the road 5. and then proceeded to tell me not to waste his F@cking time. before he hung up. so if you get a call from 0488 823 539 be prepared to be sworn at.
