Received a call from this number earlier stating I had signed up for a $50 discount voucher for wine. I had not done so, and asked to be removed from the list, at which point the caller asked "whether I just liked wasting everybody's time" (a bit rich coming from a spam-caller!). I called back later to get the name of the company to lodge an official complaint, and was called a "d*ckhead" by the same person.

I called back number (03) 8752 4968 rang 5 times then goes to busy tone.
