I called back number (03) 8372 3180 reached voice mail but did not say for what company.

I called it back & got an automated service. It said they were calling about deals for internet & telecommunication deals.
Thankfully I didn't hang up immediately as it gave options to have your number removed & added to their "do not call" list. Great feature :-D If it works.... Time will tell.

Telecommunication company offering deals
