Wow! When they called it snail mail, they weren't joking.
Got a reply yesterday.
Essentially, the story is the information is collection and maintained by Google in the U.S. - where I basically have no data protection rights.
They did seem to suggest that I wasn't using the 'proper legal channel' which was irritating - though I would have said that when only 1 contact address is given then that is the proper legal channel - which I contact at considerable personal expense.
Anyway, I might just e-mail them (now that I have an e-mail address) and see where I get - which I suspect at this point is nowhere (not criticizing Google - if the information is in the US , then fair's fair.)
