Never received day one year one background

I received an email stating I should have the Day One Year One background. It tells me to go to settings...my xbox.... achievement art. The background is not there. I contacted support and I was told to post here to have this issue resolved. Please send
me the background. All of the other items contained in my email are working just fine. I really want that day one background!! Thank you...

Question - Year One Promotion - Cannot find Day One Background

• I received my "Year One Celebration" e-mail yesterday.
• After clicking the link provided, I was taken to a page that lists what my "Gift Box" included.
  
• On this page is listed a "Day One Background" that is "Exclusively for you as a Day One achievement holder."
  
• It states that to get/use this background I need to "Go to Settings > My Xbox > Achievement art on your Xbox One." (I assume that it means "Go to Settings --> My Xbox --> My background --> Achievement art .
  
• Upon going to the "Achievement art" area, I am unable to locate the Day One Background.
  
• I was able to access and use the Year One gamerpic, so I know that these items should have been installed.
  
• How do I find the "Day One Background"?
• Has anybody else found it?
