I called back number (03) 8820 8052 spoke to a guy who said doing telemarketing for a company called ARS.

Sick and tired of these nobheads ringing. Get a real job.

Missed call, called back and no answer. Went back through my call history and saw that I'd had a phone call from them previously, they were selling insurance

I blocked their other phone number, now they are calling me on this one.....
Bloody telemarketing

Called my work mobile a bunch of times. Telemarketer! Added to my reject list

Called it back. Some non-australian answered stating he was from ars. Multiple calls from them

Rings, no answer. Possibly a robot checking connectivity.

This number has called me so many times I installed a callblocking app. When they just tried to call me now the app blocked it, so they sent a text with one word:' why?'!!! Very persistent and trying to trick me into texting them back now by acting all familiar!?!

Annoying Telemarketing
