Indeed, the mistake was made and inside of a month is being corrected with a free replacement for the defective discs. Whatelse do you want? For CBS to personally come to your door, say they're sorry, and give you a brand-new copy of the season along with an advanced copy of the next season? And, oh, the super-secret plan they have in doing DS9 that's not public yet followed by a blow job?
It's being taken care of.
