Did not answer and did not return the call, no message left. I am well beyond calling unknown numbers that do not leave a message.

Caller: ipsos

after making a NAB rewards purchase (shadow managed by IPSOS group) seemingly has also shared my details with their ipsos affiliate here. Ipsos are a global marketing and research group. I unwittingly signed up to this from the T&A with nab rewards. unsubscribe as per previous comment.

Called but left no message - based on other messages here i now have blocked number

Caller: Iview & IPSOS Market Research & Social Data Collection Agency

I phoned back & listened to their recorded msg

Caller: Carol

Claimed to be IAB performing a survey on behalf of IPSOS card (if I caught it right).
Apparently they sourced my mobile from samplepages.com.au.

Called a few times but hang up and dial myself with no connection

Caller: IPSOS Market Research

They are exempt from the "Do Not Call Register" because they are not considered telemarketers. They do buy and sell personal information and they will make money off of the data they collect from you. Blocked.

Caller: Someone who I couldnt understand

I could hear a rooster crowing in the background. I could not understand what the person was saying. I have reported as scam and blocked the number.

Another caller who did not leave a message SCAMMER

Phone flaged called as suspected spam, so I didn't answer, caller didn'tleavea msg.. But saying that, I no longer answer numbers I don't know.
On reading the comments here, I'm glad I did..

A lady called claiming she was from IPSOS and i could hear she was driving in a car.
she asked if i would complete a survey. when i said i wasn't interested she asked if i would answer 3 questions. they were: my age: my gender: and what smartphone i use the most.

Caller: Marketing Research Company

They have called approx 5 times over the last few days and have never left a message.

Returned the call and listened to their message explaining that they are a marketing research company.
