Wish I could get 12 free back issues

According to the website, when you download the app, you will get 12 free prior issues. I purchased a yearly subscription, received the most recent issue, but none of the prior ones. I have emailed twice and used the Contact Us form via the website and received NO response. Very unhappy about the past issues and the lack of communication from the magazine to get this resolved.
