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 just received an unsolicited missed call from this number today. First time.

Never call back unsolicited missed calls without firstly searching the internet to find out if the call may be a scam.

i keep getting this call at least once or twice a week and it only rings for two seconds then hangs up its really anoying me!

I too am a optus prepaid customer and recieve about 3 calls from this number per week, they never leave a message. It's very annoying. I'm going to change to another network. Optus suck!

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??

I received a missed call from this number about half an hour ago and I to an an optus prepaid customer???
