While I certainly don't know what transpired on this flight, I must report that on every international flight that I have been on with a major carrier (and AF is certainly one), all cabin announcements have been made in both the language of the originating country and in the language of the destination country. Thus, while this flight may not have been staffed with CC who speak English, I can't believe that it had no Spanish-speaking CC. Of course, whether these Spanish speaking CC actually made any announcements, I cannot opine.
