Well, I'm a relatively new poster, but decided it was time to speak up based purely on the experiences I've had with Canon's customer service, since, at it's core, that's what this thread is for.
Without fail, every time I've sent something to them for repair, items which should be well-within warranty (both based on time elapsed from purchase date, and for the issues experienced), I've been submitted an estimate, usually in the $250-350 range on the initial pass review by them. Only after contesting their appraisal, do I ever get anything worked on without any charge. To me, that's them saying that their product is without flaw and that I must have done something to prevent their gem of a device from working. I wonder how many people just pay the fee and don't contest it. I've had to go through literally hours of calls between customer service and their factory service reps to get to the point where they finally will say that they'll fix it free of charge.
I'll be the first to admit if I've dropped a lens, camera body, or poured water into a printer - I'd expect to pay for that type of repair as it's not a defect of workmanship/materials. I've never done any of those and then sent it in for repair hoping it would be covered by warranty. Makes me wonder if that's what's happening so often that Canon is turning their backs on honest customers with honest warranty claims. The very fact that there's possibly some known defects in their equipment and that we're potentially paying for it, to be honest, pisses me off a bit. So I'm not actually very sorry if you find it hard to hear us "newbies" moaning about customer service or warranty repair policy especially with the literally hundreds, if not thousands of dollars some of us have had to spend to get items repaired, I guess not everyone has the same experiences you do.
