I called back number (02) 8789 4000 rang once then gets disconnected automatically.

Caller: Aztec IRI shopper panel

They are legitimate
IRI supply scanners to shoppers so they can upload their purchases for survey purposes
They generally ring to check how you're doing or if there is an issue with the scanner
I don't think they cold call people who haven't already signed up and have one of their scanners

Caller: IRI Shopper panel

I had a scanner delivered yesterday. I was contemplating phoning them up as I was attempting to sign up, I am already registered but not sure how to use the scanning device they sent. I guess they are being helpful. Not a scam or prank, as I know I have already signed up with them.

Aztec are a company who supply a scanner where you scan in your groceries. It's like a survey site and they give you points for participating. They usually call if there is a technical issue with your scanner and they're letting you know that there's a problem. I've dealt with Aztec for many years and they are legit.

The caller is aztec they supply scanners so u can scan your groceries so u can do surveys not 100% sure if safe after the news seen saying places are scamming for information. Be careful. Im now going to send my scanner back because i am to worried
