This number, and most others starting (02) 8001 3000, are all part of MonDial fundraising which makes it money getting you to donate to their charity clients. ASk them how much of your money goes to them.

Just got one now and number is (obviously Australia - I'm in NZ) 0061 2900 70300 but on calling them back the answerphone is Mondial Fundraising.

Yup, count me on the wagon. Got a call from the same number as Maz, and same thing. Hope they don't call back. Grrrrrr.

Had numerous calls from this number and others presumably in the same group over the past few weeks on both my mobile and home phone numbers.  No one ever leaves a message.   I'm on the no-call list so assume that it's an organisation with whom I've had previous dealings and is therefore exempt.  Most probably  fundraising for one or other charities that I have donated to in the past.But it's reached the point now where I consider it intrusive and would not donate on principle even if I actually answered their phone calls (I'm screening everything at the moment).

Heart Research Institute. They have also been calling from (02) 8001 3046, 3051 & 3015.

I received a call a couple of minutes ago from this number too and I've never seen this number before. I'm not too sure why but I picked up to respond, but the caller just hung up. WTF? It sounds like everyone else who posted on this forum has had the same experience. I'm glad that other people on the forum have confirmed this number to be safe as I was initially worried that this could be some sort of phone scam. But this doesn't stop me thinking that this is annoying and an invasion of privacy.

i've got that too. still getting it even though i'm on a no-call list.... i did some research though.when you call them back, you get a message saying you've called "Mondial Fundraising Communications" and that no one can take your call right now. funny that. a bit of googling later shows that Mondial is a company that's part of these guys - www.thedialoggroup.com/ . so i also tried to email them to say "stop calling me." the email just bounces back. funny that, too.given the name of the company, i think it's safe to keep ignoring them. i just wish i could tell them what i think!
