Identified themselves as calling from Australian Business Registration & as there has been a large amount of interest in my business recently (I am a tiny locally only based small business) the wanted to place me on there directory for a fee. When questioned where they were based, he said Sydney & that he was using a Internet phone which is why the phone number looked strange. When mentioning I was on the Do Not Call Register, he got defensive, arrogant & argumentative, then hung up.
