Query: Missing DVD #5

Buyer Beware. My child just started 6th grade. I ordered these dvds early to be prepared. Well, the set is supposed to come with 6 DVDs and one companion CD-ROM. I just unwrapped the plastic and DVD #5 is missing. DVD #5 covers Algebra Equations which are the most important lessons of the set. I am really disappointed. I got ripped off $119.00.
