I called back number (02) 8966 5529 spoke to a guy but did not say from what company.

This makes sense to me, as I did the same and received a call as well

Caller: Freedom

I had a few similar calls from different numbers including this. One indicated it was Freedom Kitchens, same as the post on 7/12. I had filled in a form on their site so I could download a catalog. Not sure it's quite unsolicited, as I suppose I agreed to receive the call, but annoying that they don't leave a message or indicate who they are in their voicemail.

Keeps calling once they have your number. I’ve asked to be removed from their calling list several times but they keep calling from different numbers
