Cracked front window

I have a 2005 topkick pickup that i purchased in aug 05, so according to the warranty info my truck is still under the 2 year bumper to bumper unlimited mile warranty, right, well i took my truck to my local dealer because of a cracked front window that shows absolutely no signs of it being from a chip, which the service guy agreed, but said he would have to check with thier service rep. a couple days later i get a call from the dealer saying the dealer rep denied it. how can he do this? he didnt even look at it. 2 year unlimited mile bumper to bumper warranty. anybody have any ideas on what i can do?
