My Facebook account was disabled

Hello,



Facebook disabled my account whithout warning me or sending me anything for underage, I’ve tried getting in touch with them but no avail, they keep sending me link to help but the don,t and it says to put in my card details which I’ve never done befor i,m so sad for there are many relatives and friends keep me in touch by that account. I try so many ways not to behave my self bad nor to display bad images or words,  even i remove those who like saying explicit words are contents but my account suddenly disappear anyway,  when i tried to have a touch with my relatives and friends at that night. Please Sirs/madams, at least give me a clue what mistakes i have done and soon give me back my beloved, I account thanks so much and god bless you
