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.....

This number keeps calling me

Its Optus ... Not sure of its legit or not. They knew my plan had expired and what plan I was on. Still told them I wasn't interested. I don't trust people who call me. I call them if I wanted to upgrade

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.

Optus called as my contract had expired and they wanted to sell me a new one.

Its so frustrating!!!

Answered once Said not interested, STOP CALLING ME!
