0401 263 583. Has to be a scammer. All calls not previously stored in my phone by me,are auto sent to voicemail. This number left an empty voicemail of at least 30sec. After googling the number and finding the same issues in here, the number is now blocked. Legit businesses will leave a message,name and contact details.

I answered the call, guy introduce himself as Mark from "somewhere" but the call was disconnected and they didn't try again.

Also received a call from this number which I didn't answer. Seems likely that it's a scam.

Message This Mail box is full- obvious scam

Caller: "Future Insight", likely scam

This number called me out of the blue and claimed to be following up on a call from 16 months ago. I have no prior records of being contacted by this person. The caller was male with an Australian accent and was quite chatty, but insistent about getting information from me.

The detail of the call was that they wanted information to check if I was eligible for some kind of government scheme related to superannuation. I am very suspicious any time an unsolicited call starts asking me for personal information so I ended the call pretty quickly. I looked up the named company, "Future Insight", and while they have a website, there is no ABN, no indication they are registered with ASIC, just a bunch of generic words and some fake-sounding testimonials.

Was a lady. Background sounded like a call centre with lots of chatter. She said from QI investments (i think) and was very persistent even after I said I have an accountant. Wanted to show me tax incentives and how I can maximise my investments.

I had a call from this number today, answered the call, but no reaction.

It call me this morning. When I call back, the message box is full. must be a spam

Rang back just hung up then this mail box is full

Caller: Scammer???

0401 263 583 This number called my mobile multiple times since last week! I didn’t answer and didn’t call back. If it’s real person for real business for something important should had text to explain. Must be scammer! Blocked this number!
Since the Optus cyber attack I received a lot more calls and text from numbers that I don’t recorded.
