FORD EVADES WARRANTY PAYOUT

Ford worst warranty ever. Once again Ford doesn't honor their claim were they advise that their exterior trim is not covered by the Warranty and therefore the FADING/ DETERIORATION of it is due to negligence and not manufacturing defects. Sad part is my claim was for exactly that and FORD rejected my claim without even investigating.

I need to ask Ford how can you reject a claim without investigating the matter but give feedback that its fading due to inferior / incorrect soap used to wash the vehicle. if this is true can ford prove this ?
