It's Optus.

(03) 9982 8800
don't bother answering, they hang up when you pick up. I had missed calls daily from this number over 3 weeks.
Bastards!

I have been getting missed calls from this number now I guess because I haven't been answering calls from (03) 9009 6600 (which is meant to be Optus too). They have been calling everyday, sometimes twice per day for the last 10 days!! So annoying!!

They obviously have no concern or respect for the Do Not Call Register, as I'm registered and keep getting calls from this number regardless. Idiots.

This is another Overseas marketing scam using a digital number that phones thousands of mobiles. Register your mobile on Australia's Do Not Call Register so you mobile is blocked from all future marketing/cold calls.

I got a missed call from the number. How is it possible that when i call back, the automated message says its disconnected???? Not helpful

These fools thought that they had one over me.....idiots!! They claimed that my optus contract was up and wanted to know what I wanted to do about it, I said to them that it was impossable and that this call was a scam!! They didnt like that and hung up on me.....stuff them!! Bring it on' I dare you a..holes to call me again!!!

This caller doesn't speak when I answer so I came here to find out who it is. Very annoying. Wish iPhone had a blocking feature.

Since I stopped answering calls from (03) 9009 6626, I've now been getting calls from this number... which I will also never answer.

These a**holes are doing my head in! How did I get my number for start! I can't understand why the regulator can't do something as it seems to be australian landline number to the should be a physical address as well.

Keep getting calls from this number at the same time each day. They don't leave a MSG & I do not answer!

Annoying bastards, they don't speak English either

Just add the number to a contact and if your phone can do it add that contact to your blocked list. I now have 6 different numbers under my blocked number & I dont get repeat calls.

i get about 3 missed calls a day. they never leave a message they call for about 4 weeks, have a break and then a similar number calls again ill never answer

Spam im on do not call register.. it stoped for 3months now its back

Arses need a real job

Sick of this number continually calling me as well as (03) 9009 6645. Ive told them dont call my number but yet they continue. Ive also noticed my credit goes when they call me how is that possible?

Repeatedly getting calls from (03) 9982 8800. They have now switched to (03) 9009 6647.

I too, don't answer this number.

It's so anoying having this bloody phone calls 3 times per day for a week.. Let's do something
