yup, it's one of those.
Persistent bastards, also tried it on calling from 6100 5356, -5355, -5307 and 6122 0479

After half completing a fake ALDI survey, I have received calls from this number twice, along with numerous calls from other numbers in past days from QLD, ACT, NSW & TAS, including:

(07) 3077 9387
(03) 6122 0479
(03) 8609 0699
(02) 8015 6971
(02) 8599 0144
(02) 6100 5399
(02) 6100 5356
(02) 6188 5917

Its annoying call, blocked them = (02) 6100 5356, (02) 6100 5399, (02) 6188 5917

Me too - blocked them and now I'm aware. Thanks everyone for posting this.

Received well over 20+ calls the last few days, they've even started calling via No Caller ID.
I'm on the do not call register though so can report the numbers that showed.
It's quick and free to do so to your own numbers, which I recomend.
They will ignore it and still call but you can then report them.

Continuing to block! Called from (02) 6188 5917, (02) 6100 5356 and now (02) 6100 5399.....wonder how many more extensions will call before they get the hint?! FFS

I've been bombarded with marketing calls and emails for about 3 weeks now, apparently I have completed online surveys and also entered a competition to win an iPhone7 (which I have not done) which entitles every telemarketer to my details apparently! My blocked caller and email lists are huge!

Thanks @Bec for the following information - The calls are from Brands of Choice - Competitions (http://www.brandsofchoice.com.au/competitions) and you would have had to subscribe to receive the phone calls. Subscribing may have been from an email or a link on facebook.

To remove yourself from the phone/email/postal database;
Call: 1300 257 528

Your number was sold to this telemarketing company by Mark Halstead from icumulus marketing company. Call him to remove your number from the database directly on 0413 154 784 or the office on (02) 8262 8070.

I've called them & emailed them, they simply wont stop. I'm on the register, I've reported them and blocked them. They are an absolute Nightmare. I'm at the point where possibly the only option is a new number.

A woman called stating i entered in a competition. immediately blocked!

Who is this caller ringing constantly (02) 6100 5399 Canberra and (02) 6100 5356, (02) 6100 5317, Well I guess I just keep blocking :(

This is a sick joke. I have recently been getting a whole bunch of telemarketing related calls of which I do not answer. This is one of them. I am putting this down to probably a Coles $500 gift card prize.. Soon after that these bastards start coming out of their woodwork.
There needs to be a way to digitally announce the name of the owner of the caller on their caller ID service and a way to block it at the exchange. I receive hundreds of telemarketing calls every year and just hang up....
Time to request a new number !! Telstra needs to get their act together to install proper identification and blocking facilities.

I've reported them. I am on the do not call register and have calls from this number and many similar to it all week. Very annoying

I called back. lady said I had recently entered an online competition, I said no I didn't, lady said ok bye and hung up.
they just scamers...

telemarketers

didn't answer as I suddenly started getting calls from interstate numbers.

Brand of choice, they are an online giveaway thing, they say they are sydney australia based, this number (02) 6100 5399 is a canberra number, the woman who answered said shes in south africa..i told her i dont understand how that works and told her shes fulkl of herself. and she hung up.works gonna love that phone call

On Do Not Call Register but still receiving persistent calls from (02) 8599 0144 and (02) 6100 5399 and now they have resorted to using a No Caller ID number.
These are really annoying!!!

Yes, yet another pesky caller blocked.
