Malicious iCloud Address Tormenting Me on Facebook

I have 3 Facebook pages which have been taken over by somebody with an iCloud address. In the past they have posted on the crawl: ads leading to "Page discontinued", extremely offensive photos, such as a man being hung, a dead cat, a baby with skin disease, an elephant being slaughtered, etc.. Now they pretend to be nice, post my content but won't let anyone visit. I can't deactivate my pages because Facebook says I have no pages. That address has the pages, but I am hog-tied because I don't know the username or password. The entity has also built more than 3 fake pages on Facebook meant to entangle me and prevent me from advertising. Facebook has at least taken them down for trademark violations. How do I stop this? Will Apple help? I'm selling my company and can't transfer the pages!
