why are they calling me ..my phone number is on the DO NOT CALL REGISTER...

Yes I have a comment! STOP RINGING!!!

Oceania, a sales outsource organization employed by Optus

I actually have a friend who works for this company, it's OCIS not OSIS. (oceanic customer interactive services) an australian based and owned company with 2 overseas centeres in Fiji and new Zealand.
It is a 3rd party outsourced company who handles the bulk of Optus's recontracting work, and inbound Optus sales overflow.

They prodominanty call customers at the end of their contract and remind them they are eligible for a new phone/plan or other loyalty offers.

No more a scam than getting a call directly from Optus trying to get you to renew your agreement.

I think you all need to calm down just a little, your identity can't be stolen with a name and date of birth id check (which is done for your own safety, to male sure it is the account holder who is agreeing to the renewal)

Hi, I seem to remember looking this number up several months ago when I had a spate of calls from that number.  Other people were saying that it was an arm of Foxtel trying to sell you stuff and unfortunately once you answer that number, it keeps ringing you.

Just got a missed call on my mobile from this number today.

My contract is up for renewal that number rang me yesterday, I missed it, but they haven't called back

Hi whocallsme fans, What happened to me: I got a call from (03) 9982 8802 this afternoon on my mobile. The lady on the other end explained she was a representative from OSIS, or at least I think the name was OSIS AND that she was calling on behalf of OPTUS. She offered to HELP ME renew my service contract with OPTUS, offering a new modem, magazine subscriptions etc. all I had to provide was all my personal details - recorded by them in my own voice. She was very confident and assuring - I on the other hand was getting just a little suspicious. I asked her to call back later (which she did) and in the meantime called OPTUS. No surprises there - 1 ) they'd never heard of OSIS 2) OPTUS absolutely does not engage third party companies to manage customer accounts 3) I was thanked for the information which would be forwarded to thier own security department.It appears IT IS a sophistcated SCAM the point of which is IDENTITY THEFT !!!!*****BEWARE*****BEWARE*****BEWAREI don't know if it will do any good but I waited for the call back and confronted the caller. I told them point blank that I had called OPTUS and I knew they did not represent OPTUS, which of course they denied. I persisted, telling them I did not believe them and not to call again.:-) Good rule of thumb to survive the Digital Age - DO NOT GIVE ANY PERSONAL INFORMATION OVER THE PHONE UNLESS  1) You called them AND 2) You are certain of thier identityIt's NOT unreasonable folks. Bye for now

They've called me 6 times in the past 3 days, always at bad times so I can't answer to find out who it is. I think it may be Optus calling to see how my service is going...
