Fabby,

While we are sorry for whatever problems your friend may be experiencing, this is not the proper resource to try to get them resolved. This forum is for the discussion of technical issues with FINAL FANTASY XI itself. Since you are having problems with billing, you will need to resolve those problems through the SQUARE ENIX Support Center. As this situation did not involve any technical trouble with FINAL FANTASY XI itself, we have gone ahead and locked this thread.
