I called back the number (08) 6260 2111 and reached vm that did not mention the company name

Asked if I was the owner of my business and immediately hung up after I answered.

It's shopper dockets. The whole number range (2100 to 2199) is them.

They asked for the marketing manager. I asked what it was regarding and they apparently couldn't hear me anymore, and there was odd clicking on the phone before they hung up. I called them back and had the same clicking when they answered.
