I did all the steps suggested on King's Care email and also checked the postings of other members in this community.
I was originally playing Candy Crush Saga (up to level 707) without a King account in my Android phone and when I accidentally trigger the Facebook login, I lost all my progress. Based on the recommendations I saw, I need King's customer support to resume my progress back to level 707. Can someone from the Customer Support please respond to this request for action?
