Did not receive swgoh apple gift card rewards

I have been trying to get your customer support to help me with this and they have stopped all communication. They will not acknowledge me after sending me unrelated articles and telling me that Apple is responsible for this.
I bought the $50 Apple gift card through Target and checked all of the requirements before purchase. It was not a holiday gift card and I bought it within the time frame. Immediately upon applying the funds to my account I received an error message stating that I would receive an email with a link to the bonus content within 7 days. It has been 8 days and still no email. Will someone please help me with this as the only reason I bought the $50 gift card was because of the advertised bonus content for SWGOH. According to the support at Apple when I applied the funds, the App Store “sent a request” to the developer for the email and it was denied most likely due to an error. I’m not asking for anything outrageous here. Just what was advertised. Customer service through the game app has been incredibly unhelpful and outright condescending.
