This number called many times (12-15). They pretended to be OPTUS and asked for personal information. They are probably part of an identity theft ring.

Not so much a comment about this number, but telemarketers in general.
If they are not from this country and you don't want them to call back, don't simply hang up or put your number on the do not call register, be EXTREMELY racist. It works for me.
Personally, I don't care where someone is from or what they believe, but I use racism ALL THE TIME to upset these mongrels.
Only problem is, I enjoy doing it, but they don't call back, so I gotta wait for a new call centre to open up to do a new round.

I have been getting calls from this no. but told them that it's the wrong name & number, so we will see if I get them again. it's now the 5th day in a row.

who are these people? ive had 5 missed calls from them and they leave a voicemail but with nothing said and when i ring back its an automated message

Oh and that 02 number I was getting was (02) 8019 9700, I forgot to mention.

I get called at least once a day from either of these two numbers(02) 8198 3820 or(02) 8835 1200They won't stop calling, i don't answer or i will answer and leave it on the table beside me until they hang up.I believe it to be optus promotions.

I have been receiving calls from this number approx twice a day everyday for about a month. When I finally answered the phone the guy discussed whether I used social networking sites and internet blah blah on my phone and then asked whether or not I would like an offer of 25GB per month for $5. He then said he needed my personal details to confirm that I was who I was (he's the one that called me!). Anyway, I said no because he sounded dodge and asked him where I could view this offer online as I wasn't going to sign into anything without reading the terms and conditions. When I did this he hung up on me!!!!! (Hopefully he wont be calling back!). I have emailed Optus and expect a response from them. Regardless of whether or not this is legit, I think I will be seeking a different provider when my contract is up.

Keep getting missed calls from this number.  Not goin to answer them and considering I'm on a do not call list they shouldn't be callin me anyways!

I'm so glad I found this thread! I was puzzling who was calling my mobile everyday since last week. I answered non of these calls as I don't know anyone from 02 area. I'm also NOT an Optus customer, so I am not sure how they got my number. Is anyone here with Optus or previously with Optus? Just curious.

I have been getting them everyday for the past month, I am not ever with optus, i am on a contract with virgin, i'm not quite sure what they think they are going to achieve harassing mei know its just their job, and it is NOT the staff's fault.. its the company
