Can't I gquit but I am still in the guild

I /gquit but for some reason i can still open the roster and see the guild i'm in although it says no one is online but I can talk to them and see them talking they've tryed to reinvite me and kick me again but nothing's working so i'm sortof stuck in limbo. Also my faction change went up around the same time this happend so any idea? I'd love to be able to faction change but i can't leave the guild.
