From what i experienced is that the answer is no they will not send you the battery grip, because it was/is part of a promotion and when they "bundle" accessories with a promotion it has to be purchased as such and they have special codes for these bundles that have to be entered during the purchasing process. Basically they cannot separate the items form the camera so if your "bundle" didn't include the battery then unfortunately you lost out on that. The only thing you can probably do is to return everything and re-buy everything with the new bundle. Not sure if you can do that or not and also keep in mind that there are restocking fees that may come into play when you return certain items.
