I keep receiving calls from Optus too and im prepaid. They call me at home and my mobile, and i also get constant sms's about plans and all sorts of optus deals. But i have never once used them! How do i stop it??

Just got a missed call from this number and almost called it back, thankfully I googled it! Am also an optus prepaid customer...hmmm

i also am an optus prepaid costomer and have recieved a missed call from this number....

I have received a call from this number twice now, first time a few weeks ago and again today. Luckily I didn't answer each time. No message left.
I am on an Optus prepaid account. I think I will also change. I don't want to receive calls from Optus.

Another optus prepaid customer who received a call from this number.. i didn't answer it and it just rung out.. rang for about 15 seconds

i got the exact same number pop up. i called them back and it was like a group of girls giggling and clueless. i got this call again today and a few days ago. i dont think its important.
