Have been calling both my mobile and land line - 5 calls already this evening. Haven't bothered to answer as they don't leave a message

I expect they wanted me to call back at great expense!
SCAM!

This has to be a con job / scam. the number called me with a short three question recorded message survey allegedly enquiring on an important issue affecting regional South Australians. The first questions relate to age and gender. I didn't answer any of them and didn't proceed through the survey. The survey doesn't identify who is conducting the survey, If I don't know who I'm talking to I provide no comment.

this was an automated voice message survey about 'matters important to regional south australia' that did not identify the caller and the first question asked for age and gender at which point I hung up. Possibly a scam as no identifiers
