the rubber bottom of the macbook has fallen off

I bought my macbook about 2 years and half ago in China and am currently a student in the UK. I found the rubber bottom has follen apart from the device and am rather upset when I entered the series number via the website and found that the device was excluded in the free replacement scheme because it is a Chinese model. It is totally unfair because it is non of my faults. It is the problem with the material itself. The rubber bottem cannot stand the heat when the device is running. Can someone just tell me what can i do now?
