Has been calling 2-3 times a day for the passed 2 weeks. Obviously on a dialler and more annoying than anything.

I received the calls several times and once I picked it up they either hung up or just kept silent. It's really annoying!

they just rang my phone and started yelling at my 5 year saying that she was me.

This number called me 3 times today all during work hours and im unable to answer but reading all ur comments im not goin to answer it

They call me once a day for about 2 weeks at least 3 times a year it's been happening to me since 2008 so no I don't think they will stop I go with the general rule that of they leave a voicemail it's important if not I just keep ignoring them

I have also missed a few of these annoying calls, just called 'em back then to a pre-recorded message to tell me they where calling to check if I was happy with the service I was recieving.. :/
If there was an issue, I have a phone and I know how to speak, so i can take care of it myself. I'll answer next time they call and inform them of this.. there is no need to call flat out, I got other sh*t to worry about!

It should be easier to block numbers on smart phones for this exact reason! It's harassment. They call at the strangest times, dinner time or late on Sunday evening.. Optus would never do that.

This number has been calling me for 2 weeks everyday sometimes 2 or 3 times a day I have never answered it because of not answering unknown numbers but now I am trying to get in contact with this number and no success

I get 3 phone calls a day from this number, hangs up as soon as I answer, so annoying. I have asked Optus to remove me from their call lists in the past, obviously they don't respect that

Called me today too, Idiots!

Yeah this number keeps calling me too for the last few weeks lately around three times a day. I never get to answer it because I'm at work. I try calling back but all you hear is silence and they hang up.

Have ignored three calls from this number in the past two days. Surely these douche bags know that majority of us aren't going to buy their dodgy product or make a donation to their bogus cause. Anyone who does deserves to be scammed!

I have been receiving calls on both my mobile and home number from this number several times a day for the past 2 weeks. I will ignore it from now on, but it is very annoying

they just called me, im scared to answer sounds very sus

i have a silent number and have also received calls from this number.

I receive the same calls, they ring me and then ask for identification. I dont give them any personal info, they should know that if they are Optus as they hold the contract. The caller asked me how much a month do we pay and what contract do we have
If she was from Optus she would have known all of that info and had no need to ask. I asked her what contract we were on i was told that is private information and she could not tell me, sounds like a lot of BS
I dont think its Optus just some scammers!!!!!!

yep same thing happend and im with optus... hmm makes you think eh.

I have had 3 calls from this number over the last 24 hours. 2 at dinner time last night and 1 this morning at work. Does anyone know if they give up after a while or if there is anyway of blocking the number?

Yep called me too, called back and nothing on the other line? I'm with Optus also

have been rung by this number appoximately 30 times over the last 2 weeks. Is there any way to get them to stop? Thanks to those who have posted here so that I know who it is.
