How do I get in touch with the Facebook legal team?

Before Facebook put out their ”/(name), e.g. facebook.com/fritolay” access, my company put in some paperwork reserving it. Instead of having a clean address, we now have number and all that jazz after the forward slash. Now, we can’t access it because it needs to be released. I want to contact Facebook legal and get to the bottom of this. Or other ideas? Thanks :)
