I appealed for a unban on the band group and got unbanned according to the group, but my chocolate clash profile stills says that I am banned and hence no clan is accepting me.
They told me to contact here
Please read this https://forum.chocolateclash.com/d/10-how-to-appeal post and make an appeal post with the given format. Seems you got unbanned to join FWA but for getting unbanned from GFL, OL and 1945 you have to get ban removed from here.
