Harassing Optus telemarketer who will not go away

Despite being told that I'm not interested, Optus persists in calling me from this number & one other number.

always call after 5pm. Leaves a vague messsage. Glad I checked!

Calls everyday without fail! Drives me crazy!

They have called me 3 times while I have been at work. And again just then, I figured I should look it up before answering the phone. Seems very persistent and annoying.

I get a call from this number at least once everyday and they just hang up when i answer, so i decided to not answer, i have worked out that they do not call on weekends.

Received a missed called

calls all the time, definitely a scammer.

Receiving calls every week from this number. Answered one and was told it was Optus, but, they then asked me to tell them my postal address as confirmation. Seemed like a scammer.

This person is a scammer beware. It is not Optus.

got a missed call from this number tonight at nearly 8pm !

Just Got a call then - They hung up as I did not answer quick enough

Me too! They've called me twice.

Got a call, went to voicemail, message left, turned out to be on hold music - very annoying

The call me regularly, but I am not able to answer as they hang up within one ring. I will receive a minimum of one of these calls per week.I am an Optus customer but I have never been able to answer the call before they hang up.

It's a company called Oceania Customer Interaction Services.Outsourced call centre for Optus I think...they've been calling me too, very annoying!

Lots of missed calls from this number. Yesterday i answered and woman with accent asked for me by name. They started with the how are you etc and i said i was in a hurry and what did they want. She hung up on me! I am on the do not call register so i am about to report them.
