Does Apple have a Consumer advocate?

I have had several mac computers, and still run 4, office, home etc etc

For two years I have been trying to register one iMac computer and its warranty, and have never been able to. I do not think a week or two has gone by with out me contacting either APPLE or the Store (London Drugs in Canada) on trying to get this thing registered..

I have faxed the receipts in several time to apple, as has the store I purchased it from, they have contacted their sales rep to try to have him fix that I have been told several times when I called into 1-800-sos-apple that the problem will be resolved, and that it takes 7-10 days to go through the system, every support person I talked with understood the problem and they were all very pleasant (except for one, who told me if I do not like how apple handles problems i should purchase windows machine, I already own several, and that apple has a lot of customers and one person does not matter to them)

Is there ANYONE at apple that fixes these problems?? ANYONE.

I am just so frustrated that I can not take this any more...
