I did some research and have discovered that the company is registered as The Consumer Information Services. They are a division of Austel Marketing pty ltd.
Their website is http://www.austelmarketing.com.au
They are located in Varsity lakes Qld. They are just metres from Bond University so most of their staff will be pissed off Uni students that keep getting told I'm not interested.
The reason they keep calling is because rather than putting on file that your not interested they keep your number live and comment something like very interested call back and then set a time that will make your number pop back up in the system for someone else to call you back.

3rd time this year they have called me and asked if I want a quote on a life insurance policy.

I am so annoyed this no. rang me 2x yesterday even if i dont answer. They also rang me couple of days ago... Then this morning so early they rang me and it woke me up!!! Now I cant go back to sleep!!!! Haist hope business like this can be fined for public disturbance or annoying tactics... bloody scammer!!!

Claims to be from "National Consumer Services". Asks if I've heard of "Real Insurance". Takes some details and arranges to call back for a life insurance quote.

I just blocked them

call me on work mobile - very annoying and I do not answer.

Called me 4 times in 4 days. Supposedly from real insurance. I said I'm not interested but they keep calling.

Spam caller, been calling my mobile repeatedly for a few weeks, first couple of times on answering there was no reply so I hung up, now I don't pickup from that number

They have called me everyday for 5 days now -.- blocking this number (07) 5566 1355 immediately

Received on Government issue work phone; answered the phone from this number and they hung up. Two days in a row. Bloody annoying.

Stop calling me, I have a new baby and no time for your crap

Keeps calling more no answer. It's really getting annoying. Everyday it happen .

Multiple call per day, I answer no response then they hang up

so annoying twice in a 2 days....

Another call - no answer - stop annoying me at work

I've had the same number call me for the past 3 days. I call back straight away and guess what no answer. I will not answer it now I've seen all these comments. And block the caller.

This goose called me again. First he was silent then he said he was calling from 'National Consumer Services'.

The call was terminated by this little douchebag before I could warn him of the consequences of annoying me.

DEFINATELY a scammer.

Just had a missed call from this number and am happy to find out it is spam and have added it to my block list.

No one there on answer

They rang me when overseas but I could not pick up. No answer when I called back and then I searched via this web site. Will block them if I can.
