sounds like you need to contact your local Porsche Club of America.
Even if it's a wear and tear item, I think your rotors are supposed to last longer than 15K miles.

It doesn't surprise me that Porsche won't stand by their product. Allot of the 1st generation carbon rotor owners got stuck with huge $10,000+ claims for cracked rotors. And of course most of them went ahead and bought the 2nd and 3rd generation PCCB from Porsche despite getting screwed on the 1st gen.
That's why Porsche make allot of money.
