Bah. I rang microsoft when my key refused to work when I formatted a couple of months back
I got the old 'press 1 for emergency snacks' lark, where you HAVE to wait until they reach 'press 134' before you know which the right choice is.
Then I got a guy in India who didnt have a clue. He had a script but didn't understand the term hard drive, and it took me about 10 minutes to realise I had to call it a hard disk if I wanted to get anywhere this side of armageddon
and then at the end of the conversation he asked me if the weather was nice where I was, and then cut me off before I had finished answering.
Callcentres suck. It would be quicker guessing the damn key to begin with.
