Best Buy ripoff (Score 1)

So what do I do now? I go to Best Buy to purchase the new Bowie disc (Ziggy Stardust) only to find, when I get home, that the discs are missing. Back to BB to have them a)tell me , in so many words, tuff luck and b) please leave the store, you're too upset and abusive. And i was just trying to get these people to realize that they operate a den of thieves..heheheheh. SO, question is...what are your suggestions as to how to pursue this. spare me the 'are you sure you're not pulling a scam' cuz I didn't. Of course, BB told me to complain to the manufacturer. What? they are goning to be responsible for some backroom employee stealing at BB and resealing a bogus pack. I think not...so I await your legitimate suggestions.
