Hello @CoveCayGolf. I'm sorry to hear that you had difficulty contacting our Support team. I'd like to see if I can help you with adding a Join My List tab on your Facebook page. This feature is available for Facebook business pages and it allows you to get new sign-ups from those who are viewing your Facebook page. You do need to be an administrator of the page that you wish to add the app to. Here is a link to a Help Center article that walks you through how to add the app and another article that shows how to customize the Join My List page.
