Cannot delete ring tag HELP

Hello, I have a problem that is driving me mad, I downloaded an app (I think it is called a ring tag), when someone calls my phone a southpark character chats away until I answer, I cannot hear it only the person calling me, I only my ringtone, I have uninstalled the app but cannot remove the ring tag, does anyone know how I get it removed, orange have been no help whatsoever. Thanks
