Missed a call, called back, automated message from a private market research group.

Caller: Unknown

Kept calling me for 2 days now, and I have not picked up as my smart phone does not display the caller ID. I assumed it was not important as they have not left messages. Looking at the previous comment, I now am not worried that I missed their calls and will probably block the number.

Got a call from them today. Didn't pick it up because I suspected it's a scam. Had a call yesterday from (07) 3087 1759 which has had a lot of scammer activity since 2014 even. Seems my number is on their database.

They hung up after 3 rings

Call about survey for living in NSW. Actually very pleasant on the phone.

Missed this call and when I called back it said the number could not be connected.
