I returned a call from 0488 854 637 but the voicemail didn't mention the company name

Rang twice and hung up

Googled number at it’s a pool liner company

Dodgy! Called me at 1935hrs and I missed it thankfully. Called the number at 2230hrs and it went straight to voice message with the following message "Record your message and press # or...."
I hung up at that point.

Caller: Research agency

Richard emrs or something like that research no doubt wanting to waste my time with questions I don’t care for

Caller: Scammer claiming to be a business called “pool liners plus”

Calls at 8pm at night, when I search the number it came up as a company called pool liners plus and there listed website was in invalid.

Caller: market research bullsh*t

I never answer calls from numbers I don't know and I suggest everyone to do the same.
This number never left a message which to me is a clear sign of
a) Not important or marketing of some kind of bullsh*t
b) A waste of time calling you to change electricity provider or internet etc
c) More sinister. Sometimes these cunning little hackers are trying to get a digital profile on your voice by recording you to aid in hacking your accounts etc in the future.
Remember, if it's important they WOULD leave a message or a number explaining how you can get in contact with them and what it was about.
Don't be a victim people!
