Issues with contacting facebook support staff?

[:]]

I have an open rape case against a man, whom I used to be 'close' to. He is now posting half naked pictures of me on his facebook. I have reported and blocked him but facebook says that the pictures are reasonable to be on facebook because technically nothing is showing. However I never gave him permission to take the pictures regardless they shouldn't be online I def. never gave him permission to post them on the internet.

I have an open case, detective told me to contact facebook with the case number but I cannot find out how to do so. The only way to contact them is with their basic messages nothing can be altered in the message so I cannot address my concern far enough to tell them about the case and how he is harasssing me. Can someone send me a link to address this??


THANKS in Advanced!
