I get so many calls from "Tom from the wine club" through many numbers including this (03) 7053 3964. Many years ago, I took the call and the call got too long and Tom was very insistent. A netizen on a site similar to this said this is AI generated which makes sense on how productive Tom has been. Nowadays, I don't pick up calls if I'm not anticipating calls or if they're not on my contact list and hence I find Tom from the wine club has called if a voicemail is left. Tom from the wine club has left me messages from many numbers, including from (02) and (07) prefixed numbers.

Caller: (03) 7053 3964

Concierge Wine Club is an AI robo caller. Not a real person on other end. Had many of these calls.

Caller: Wine Concierge Club

Been getting a lot of calls lately from numbers with same preix (03 7053 xxxx). They ring and as I dont recognise the number I let it go through to Answering Machine, but they never leave a message.
Today, out of interest, and to provide information to users of this website, I called the number.
Call was answered by The Concierge Wine Club.
So prtobably not a scam (maybe) but a persistent nuisance Telemarketer.
