Got the call, the woman was very low voiced and I couldnt really make out what it was about. Except something about a "conversion", and maybe a "mac" something.
I just happened to google the number and came up with this page.
I told the person I had absolutely no idea what it was about and if she had the right number. Btw I'm in Denmark - being a 0045........ number, how people would mistakenly call such an obvious international number I have no idea.
