I called back the number (02) 9159 7953 but the phone just kept ringing

It’s not a fraud it’s noni b they are offering vouchers

Caller: Noni B

Got a call today. Said it was Noni B wanting to send me a voucher as I hadn't been in the store for some time.
And then he said he was ringing to confirm that the email address on their records was my active email address. He kept reading it out to me.
I got a weird feeling. Like the way he phrased it didn't seem normal.
Anyway, just my two cents

Why did Noni B call me on a Wednesday evening at 5:43pm. Very unusual.
I didn't answer the call.

fraud

I returned the call and got a message saying it was the Noni B Group

Caller: Said he was from Rockmans.
