Caller: Someone conducting a survey

We are not selling anything - just conducting an economic survey.
Asked if they checked the do not call registry? When advised that they will be blocked and reported the female quickly hung up

Another in the same number format with changed digits and so I answered this one and announced myself with a bogus department name and how can I help, which area are you in, would you like me to send help ?" A foreign accent female voice said "Sorry, wrong number" ... and hung-up. Blocked

Said they were doing a survey on economy. It was a lady with possibly an Asian accent. Said they were calling within Australia. I answered their questions. After hanging up worried it was a scam. Now I’m stressing it was.

keeps calling even after I blocked number. Electronic voice confirming eBay purchase. Must be spam

Missed call, no message left.

He said something about a survey, when I said no, he said he'd call me back.
