Called it back when had my number set to private, and it said it was basically a company that works for a bunch of charities

I have had 5 missed calls from numbers starting with 0451 518 *** I have now blocked all 5.
I have received 2-3 calls per day for the past week. They reach my message bank and hang up. Not impressed.

Constant calls from various 0451 518 numbers, no voicemails. Blocking them all.

here is another number to add to your list
0451 518 424
0451 518 454

I answered a call from this number today. 28th sept 2015. They say they are calling from hello fresh. I cut her off and ended the call.

The following four numbers call me every day multiple times a day and Never ever leave a voicemail . If it was really important people you would leave a message!!

0451 518 424
0451 518 416
0451 518 466
0451 518 495

and im supposed to have a private number. so im pissed - ive blocked all four of these ones.

All the 0451 518 numbers are dodgy. Block them!

Didn't answer

Thanks 0451 518 424 called me on 31 Jul 2015 as well. Not worth returning a call to anyone who will not leave a voice message. Thanks for the help.

0451 518 424 keeps calling, seems that any mobile number starting with 0451 518 XXX is a dodgey number that keeps calling, no idea why these people/machine are doing this, get a life losers.

Called me 3 times everyday, and decided to answer
0451 518 462 (no one spoke on the other end, was completely silence and waited the operator to speak but nothing so I hung up)

After that every 15 mins I get call from
0451 518 424
0451 518 495
0451 518 462
0451 518 440

0433 432 574

Hope this helps you all out there.
