It is a number used by a charity fundraising company I received this call and similar numbers after signing upto heart research institute

painful

got a phone call from this number National Sports apparently. We haven't signed up for any charities listed above. We are a business. Hung up on them. Sick of being called by scammers.

Just received a missed call from 0451 518 462 on my mobile phone. Have never received this type of call before. They dont leave a voice message. Can only contribute it to recently entering a TVSN competition online where it was compulsory to tick the box saying you will receive advertising, but can unsubscribe later. tried unsubscribing but can't find anywhere on the website to do it or help. Wont fall for this again!!!! Grrrr....

Getting numerous phone calls from variations of this number. Have signed up to WWF recently. No one is on the other end when I answer either. They call my work number and also my mobile. Not fun.

6 calls today & its a joke. I signed up with WWF yesterday. Wont do that again in a hurry!

It is Canteen - wanted to confirm details of my recent donation. Nothing earth-shattering, but also asked if I was happy with the level of professionalism etc of the person who collared me on the street. I just answered it the second time as they had not left a message the first time.

I've also been getting multiple hang up calls over the last couple of days from 0451 518 462, 0451 518 424, 0451 518 495 - no response when I answer the call and no message. Assume it's some charity as previous posters have noted. Note to charities - it's driving me crazy, and you are rapidly losing my support.

Annoying.
I believe it is canteen.

I got a call from this number - called it back and a machine answered something about api-group australia or something. Could not quite work it out. I signed up with WWF recently so perhaps this was them confirming that, as per the above note from user 'Leann'

Made contact.....it seems it is a call centre that charities use. In my case, I had just signed up to support Canteen and the various numbers beginning with 0451 518 4 were people contact me to confirm the form I had signed a week earlier. It seems they don't leave messages in case they have been given a bum steer with details
