Off on a tangent here but I purchased a Logitech mouse from Amazon. The middle mouse button stopped working but it was still under warranty. After contacting the Logitech support centre they gave me a code to give to Amazon for a replacement. I ended up on live chat with someone who did not understand what a warranty was - telling me "You have used it, so the warranty is void." 2 hours later he passed me onto someone else who immediately came across as 'not inside an Indian support centre megabuilding in Dheli'. Sorted it out in 2 minutes.
