Who called from +61 2 8917 9339?

This number called me this evening. After saying a mumbled name. Which I asked her to repeat. I stopped her and said that I had received several calls from this Memphis??? I have asked for my number to be removed from there call list. I asked how she got my number. Which she replied you answered a marketing online and you are responsible for us calling you so don't put your name down. She refused to tell me what marketing questionnaire for whom. Got very nasty putting this back on me. I don't put my phone number out there without being very careful of repercussion now. So I asked her then why after telling at least 3 other people hasn't my number been removed and then.advised her I would be reporting this number as possible spam fraud. She hung up.
