There's also the get Watch Dogs 2 free promotion that was going on, but from my experience you must buy a laptop in special packaging to qualify for any of those. On the other hand, ASUS seems to provide special via customer support redemption exclusive to several countries (SEA/Pacific, none in USA/EU).
If you did not receive a clear coupon code/redemption instructions with your laptop, it doesn't mean that it doesn't qualify. It simply means your product is not a part of any promotions, in other words those are N/A.

You can accuse them of any deeds you like.
