I just keep getting missed calls.

Guys, call the number with caller ID on. It allows you to remove yourself from the contact list. Takes 3 business days to work, but it stops them.

They keep calling every day I keep avoiding them they will get the point sooner or latter.....

Yes its Optus and McLeod's Daughter is right.i rang it back and followed the prompts to get my number taken off their list.Fingers crossed it works!!

simple b***s*** x

I've been getting calls too!!! For the past two weeks and a half at 10 am ish...That's dedication alright!

This number is "Oceania Customer Services Austalia" a marketing company for "Optus".
To remove yourself from this list, as they are relentless in calling (up to 3 times a day everyday), call the number back, you get a voice recording explaining who they are and if you'd like to be removed from their marketing list.  At the appropriate command press 1, then wait for next command and press #, once done they'll end the call.

I've done this every 3 months, Optus are about to lose me as a customer if this continues.

This number never giving up calling me~! Who is this?? is anyone have any idea who is this number??

hahah same i came to check what the number was cause it was an indian chick either wanting to sell me something or get my credit card details. i told them to f*** off. block them.
