I live in the Netherlands, and the Microsoft 'folk' call here too. It's not hard to recognize this as a scam, since most large companies won't spontaneously call their clients anyway. Besides, they do sound as if they come from India too.
If I'm in the mood, I'll string em along for a bit. And when they inevitably ask what I see, I'll reply something like: "I see dead people", or "I see a pink forest with unicorns and yellow zebras."
Pretty stupid I guess, but it amuses me to imagine what they are thinking on the other end of the line. Still, the problem is serious, and as per usual, governments on all sides seem to do little to nothing to stop this sort of phishing.
