The first call from this number claimed to be a lady from Optus. I mentioned it was not a convenient time and hung up. Since then, I have had about 20 calls over the last week and a half. No voice message is ever left and if I answer it there is just silence.

they are calling me 8 times a day (02) 8216 4900. i want to call the police.. its freaking me out. when you answer then its 28 secs of eerie silence..

it optus..... well that who they say they are

whoever this lot are, they are downright gutless and need to be dealt with...obviously noton the up and up

Can't call back either. Don't waiste your credit calling back. They will call again if they want you.

Same as everyone else. It says the phone is switched off, meaning it must divert to a mobile phone.

ive missed the call from them 6 or 7 times now... and i cant reply it, and i answered it once and it just hung up after 5 secs of silence

they call me but i cant call bak its getting annoying now that they've called on numerous accounts

received call from this number, cnt call back really pissed off

called and missed the call. cannot return phone call. annoying!

yer i get like 1 - 2 a day what is it

got about 20 missed calls in the past couple of weeks. not possible to call them back verfy dodgy.

yea call me last night as well.

Recieved the call today tried to call back, has a weird ring tone at the start then goes normal but no one answers.

I got this message too! I went through the whole exercise and whatthey'll do is try to offer(forcefully) a 24 months plan. If you don't answer, they'll keep calling. Just answer and tell them politely that you would like to stay on prepaid. :)

a**holes been calling me too. Got a call today so I answered it but just silence on the other end, no one replying, so I hung up. Thanks for the idea to save the number as "prank - dont answer"
