I agree with all of the posted comments. These people are a nuisance.

I got a call today from 0403 185 092, they said I OPTED IN on the internet with them to increase my wage, I told them NO I didn't and the Aussie girl on the line apologised and said have a nice day and hanged up in a nice way.
Something wasn't right about the call.

they have called my business and as soon as I answer they immediately hang up. Starting to worry if they are stalkers! going to block this idoit number now!

Just answered a call from the above number.

I said "hello" three times then whoever was on the other end disconnected the call.

Received 2 calls from the number this morning. First one I didn't answer, second time I did. It was an investment mob.

police ought to do something about this number. They use a long list of such numbers

Female voice. Raving and swearing. Silly as three tits. You on my block list now girl.

Multiple unanswered calls. No message. Spam?

silent caller

investment company so they said selling online

No one there when answered. Can't return call
