Caliber Collision Centers review: Local Caliber Collision center will not warranty their paint job

Had front fender replaced, and front nose section replaced and both painted to match the rest of the car, the painted fender and nose section are both fading and don't come close to matching the rest of the car, took car back to Caliber where the work was done and manager accused me of having someone else repaint the fender and nose section which is why they now don't match the rest of the car, car has not been repainted by anyone else beside Caliber Collision. No UV protection added to the clear coat?
