I received a text message from 0409 590 931 Market Solutions which mentions their phone number (03) 9372 8400 on my unlisted private phone number so I do not know how they got my private unlisted phone number. The text message relates to market research involving Sydney, Brisbane, Hornsby, Bega Valley and Wollongong which has nothing to do with me. I have blocked both numbers

No one spoke when I picked up. There was some background noise (maybe someone speaking, maybe a television) and an electrical buzzing.
I didn’t actually speak as I was waiting for them to

My advice is to download the app called "Should I answer" and then you can block numbers like this from calling your phone. I get sick and tired of these sales companies and all their tricks. Even though my number is on the 'do not call' register they don't give a dam!
