Manual Transmission problems of the 2006 Kia Motor Spectra

My clutch started slipping around 36000 miles. I hadn't thought anything about it at first, thinking it was my imagination as I had the car only 3 years. (2006 kia Spectra5. I purchased it at the end of November 2006 with 7 miles on it. ). Well, 4000 miles later I am told it needs the entire clutch and flywheel replaced. I have driven manual cars for years. The warranty will not cover the replacement ($1300) even though it is 10 yr/100000 miles as they consider the clutch "a wear item". I tried to argue with the dealer that it wasn't wear after just 3 years. I tried to complain to corporate but the number is bogus (800-333-4541). I have replaced the front tires twice in 3 years. Good year eagles and the brakes twice. It is a front wheel drive.
