This phone number: (02) 9248 0434 is calling the same time everyday twice a day. I have called back and I get every single time a voicemail for Preston Smith.
I have left two messages with this number to not call me back if this person is not willing to leave a message on my voicemail and that I don't appreciate the calls. Extremely annoying and I would love to know how to block numbers for my mobile number. I don't know how this idiot got a hold of my number in the first place.

I believe it's a company called Spring Financial Group - Financial Advisers. Sales call. I downloaded an ebook on Self Managed Super Funds more than 3 years ago and they haven't given up... but they don't leave a message either. I just ignore any call starting with 02 9248 04..

Had this number call me today as well - no VM left

Spring financial group. downloaded an ebook about investing well over a year ago -- still getting calls.

Received a call but no voice mail left

6 Sep 2016 - I missed a call from this number and called back. They are a property investment (or similar) group asking about the eBook I had downloaded. They had the wrong number, but seemed legit.

It may be a coincidence (I doubt it), but I've missed/ignored about a dozen calls in the past week from (02) 9248 0448 - no message left. Very annoying!

received a call from this number 28/07/16, no voice message left
