Page removal feedback

There is a page for a short film I worked on in 2017 that was never completed nor released which I am trying to remove. The page mistakenly has a release date, and so requests to remove the page are meet with a message that the presence of a release date is gospel proof that the film must exist and therefore the page cannot be removed. I've tried updating / removing the date first, but either get a response asking for proof it was never released or that my request goes against contribution guidelines. I've included all this info and more in all my requests but am not getting anywhere. Please help.
