There shouldn't be a reason why you were canceled, since you preordered the day the GE went up. Did you use a credit card to preorder? I know BB puts a pending charge on the card every week or so, just to make sure it has funds, and if it doesn't then they cancel the preorder AFAIK.
Both of you should relay your concerns to the BB reps over at the BB unlocked forums. They've also helped people who had trouble claiming their $50 gift card compensation.
