Regardless of what "someone" told you outside of the sale I'm pretty sure that it was clearly stated in the hard to miss red text when you bought the bundle NOT to purchase ANYTHING along with the bundle when making the purchase, so on and so forth.
That's how it always works with subs., items released later on and so forth. You gotta make sure to read before you buy.
Trying to get competent answers via e-mail or through the phone with the average rep. at DR is unfortunately usually not the best bet. In this instance however, you could of saved yourself the trouble, as again I can bet that it specifically said not to combine things.
