Panasonic warranty is useless

Last January, I bought a Panasonic Lumix camera when living in New Zealand. I was wary of buying something expensive overseas, but was assured that it came with a 1-year "worldwide" warranty . When the camera went dead in Thailand, I phoned the Panasonic support numbers in New Zealand and Canada (which of course both routed to India). They asked where I lived, and told me I should deliver it to a Panasonic authorized repair center in Canada . Very inconvenient , but I that's what I did once I returned. However, after I sent it to the repair center, Panasonic decided they wouldn't pay for anything unless I could send them a copy of the warranty card that came in the box. So now I have to pay for the repair estimate (they determined it was unrepairable) and shipping both ways. I have the original receipt , the manual, and all accessories. The warranty is still valid through next month. Why should a photocopied piece of paper make any difference? Oh right...
