How can I sync my King.com game with Facebook without losing my progress?

Somehow, I had lost my connection to Facebook; so I just continued playing the app using my King.com account. Now that I am able to sync it again, it keeps bumping my progression back down to where I left off on Facebook. How can I sync to my Facebook (so I can help and get help from my friends) and keep my progression from the King.com account?
