hi guys register to the following government website
https://www.donotcall.gov.au/
if they still call, u can file a complaint on the donot call registry, I have been also very annoyed to calls from this number

I'm in Sydney and getting calls from (02) 8003 6000 almost every night at around 6:30pm.

My advice: When you see a call from a known telemarketer number, answer it, then immediately hangup (or just let the answering machine get it). Everytime you do it costs THEM money!

If everyone did this, the telemarketing effort would yield zero results and still cost the sponsor company money. Most businesses stop investing in marketing with zero results after a while - we hope!

We have been getting calls from this number for at least two months, I answered one of the earlier calls and the lady tried to sell me cheap international phone calls. They called me by my Surname, which is croatian and spoke to me in Croatian. I told them we don't make international calls so No Thanks.
They still keep ringing and when I answered last they hang up on me, so now I just don't talk and hang up on them. When my husband answered one of the calls they tried to talk to him, but he hung up on them as well.

I am getting this call from (02) 8003 6000 at random times. Hangs up after saying Hello. Very annoying.

CONTINUOUS BUSY DIAL TONE

Received a message on answering machine Mon, 11 May 2009 at c. 1:00pm in Sydney, in loud, low-quality audio:"Will be with you shortly.......Are you interested in earning money...." in North American accent.  Then went on to say "Go to www.ccicompany.us". Naturally, I did not give them the pleasure of seeing another sucker from this country going onto their site.While I'm writing this, there is another call from same number! This time does not leave message.

called me last night and tonight 25-26/03 and no message left
