Also, there's absolutely no reason they should have given you one with codes that were already used unless they (a) forgot to remove the manual from the box if it was the only copy and some prick customer copied the codes, or (b) they took it as a return from a customer who likely complained about X reason and did not move it to field destroy as they are supposed to with all one-time use items.

I would return to the store you purchased it from and explain the situation, and if they get uppity, just politely ask for the number for their district manager. If they give you an 817 number, that's the corporate office - explicitly state you want to speak with their district manager, but only if it comes to that.

Though they may not be able to refund your money (should, but that's manager discretion), you should at least get a credit back for the item you are unable to use.
