Cast member addition declined, despite having evidence

Hello, I do have another problem, Maya. For the film Bride of Chucky, there is one actor not credited in the actual film, but is confirmed from another source. Voice actor Rebecca Brenner confirmed on her company website that she did brief voicework on the film (alongside mentioning some of her other voice roles), but the actual film doesn't credit her, just Brad Dourif and Jennifer Tilly regarding voice actors. Despite adding evidence that she did work on this film, they still declined it despite having evidence, and not doing this as a false edit, this is true. Can someone please fix this? Here is the link. (251020-222521-142000)
