My wife has received a number of phone call from this number. Know that it is probably a scam.

I phoned back - recorded message "You have reached the Cantar phone room, please leave your message".

Caller: (02) 9101 8665

I got a call from this and as soon as I said hello the guy on the line said hello and said my name. How in the world does this guy who claims to be doing a survey know my number and my name. Sounds super fishy. Blocked it and I’m changing my number.

Received a call from them, immediately disconnected when answered. Probably a spammer.

voice message saying "Cantar market research centre"

Caller: Cantar market research center

called back and the message was it's cantar market research - blocked that number immediately

I missed a call from (02) 9101 8665, when I called back I reached voicemail but couldn't hear the name of the company
