Every time I have had to call up Microsoft I have gone through the automated process and it is pain since the voice recognition doesn't work. Then at the end it dumps me to a human operator where I have to answer questions (largely accusing me of being a thief), read out all the damn numbers again, and then eventually get a set to type in.

This is especially a problem if you end up with a faulty motherboard or similar, and so can end up doing several (re)installs trying to work out what the heck is going on. Thankfully it has been a while since I last encountered a faulty board.
