Calls & hangs up, no message. Effing nuisance.

Caller: Australian Wealth Initiative

Received a call from someone who claimed to be from the Australian Wealth Initiative. This is the second time I've been called by them. I asked them how they got my number as I'm on the "Do Not Call" register. I was told that I had opted in by completing a survey or competition online. I asked them to remove me from their database. They said they couldn't and kept repeating that they were looking for homeowners under 59. At this point I told them I was hanging up and blocking their number and did.This company does not appear to exist so may be a scam.

Caller: Wealth management

Tried to talk to me about government rebates I might be eligble for
Told them I was on the do not call register they tried to tell me I had signed up for the call
I blocked the number this morning on my iPhone and it still came through tonight at 7pm
These people are pests

Scam

Caller: I don’t know....

This number rang me 4 times in quick succession. Tried to call it back, it says ‘Optus regrets the number you have called has been disconnected’....interesting as it’s not a mobile number...
