Help me with Internet Marketing

Background: We have a company facebook page with about 1000 friends and 123 likes. We used to get lots of rubbish posts with indecent photos and filthy messages. We "Unfriended" some of those people. They somehow complained against our facebook page for spamming. We are a legitimate business with professional website and pages on Google plus, linkedin, twitter, etc. Problem: Every time anyone clicks on any link to our website - instead of going to out webpage it brings up Facebook warning saying "Facebook believes this website may be spam please click or SPAM or NO SPAM. This is frustrating. We have complained to Facebook but they don't respond to "Comments" or "Reports" and nothing has been done to rectify the situation. Links to other web properties go straight to the page it's just our company website that has been somehow considered a "SPAM". Task: Can any of you Facebook Gurus or Supermen get our website out of Facebook's SPAM blacklist. We never spammed or did anything wrong. You can see on our timeline clearly. I don't approve of Facebook's customer service (non existent) or Facebook's management of trash comments and images spilled on each other without any control. But our customers go there; so we have to go in the trash heap with them. Ideally, you will know someone in Facebook office to talk to them or hit them on their heads. Any quotes or suggestions will be welcome; especially if you have solved this problem earlier.
