Iphone Red paint chipped?

I have been using iPhone 7 RED for about one month with fully covered by a TPU casing and full screen tempered glass most of the time. It seems that the red anodised paint had been chipped off from the phone body. I am really disappointed with what happen to the phone because I was using it very careful.

I have chat with Apple Customer Support since the beginning of May and it is not covered under warranty since it is under cosmetic damage. Seems that the anodised paint quality on iPhone 7 RED is same as what is on iPhone 7 Matte black. The iPhone 7 RED body paint will chipped at anytime regardless you are using it very careful. 😉
