Hi, just thought I would let you know my experience of trying to use the 2 year warranty. The staff in the camera shop (and the sticker on the box) said you must register in order to have 2 year warranty. So I registered my camera promptly and had an on-screen message saying it was successfully registered. I now have a problem with the flash and the camera was sent away. Today I have received a letter saying I have no warranty. I spoke to Nikon head office and I was told that although I registered the product I didn't tick a box somewhere that said I want a 2 year warranty so they said it is not valid. So I have proof of purchase and a registered product but they wriggle out of honouring it because of a technicality. It is blindingly obvious that I wanted a 2 year warranty and they know I have registered on their website but they are adamant that I am not entitled. I am very unhappy and cannot afford to pay for a repair. I have a Coolpix S550 and the flash does not go off. Does anyone know what the problem might be and how I fix it? All the settings are fine as they checked it in the camera shop before sending it away.
