They have tried it on with 2 key things there
but apparently this does not count for the purposes of warranty.
If they offered a 2 yr warranty this is rubbish, there is no techicality on evidence of purchase, and it stands a proof of purchase for this purpose.
Jessops response was that I should have it independently assessed
Utter nonsense, only if you reject their assessment. If you accept their assessment then they are damned by it. I had a high st kitchen company try this – their own assessor said the kitchen was fubared and they tried this 3rd p inspection in desparation to try and wriggle out of their own damning report!
Forget Nikon, carefully fill out your N1 and send it to Jessop with a letter marked Letter Before Action and registered post to the Company Secretary (look up his/her name), give them 7 days to reply or issue in the small claims. Worked for me with Jessop, EasyJet, to name but a few.
BTW Jessop are fubared, ABN Amro bled them dry before floation they never recovered from that, their ability to survive is highly questionable regardless of Canon.
