That is the deal being offered and the deal you received.The advertised price of the device was not a reduced price, it was the regular price with a Gift Card. You are looking for a different promotion such as a 10% off deal or something like that. You are not speaking to Apple here, so they will not hear your request for a different type of promotion.
There is a Feedback link you can use, although there is nothing specific to promotion feedback, so you would have to choose the device and then in the Comments of the Feedback explain your displeasure in the promotion. The only thing we can do here is explain why you see the promotion billed as you did.
Product Feedback - Apple
The promotion was actually pretty clear and you received the Gift Card with the purchase. It is just the way that it was billed where some did not understand it and thought they get both the reduced price of a device and a Gift Card on top of it.
- Upon making an eligible purchase, you’ll receive an Apple Store gift card via email. That gift card can then be used for a future purchase at the Apple Store, in the App Store, or for an Apple service such as Apple Music, Apple TV, or Apple One.
