I have the same problem posted here by LT Jay Gatsby22:
I received an email yesterday 6/13 offering a code for 160 points with the subject: "Get more of your favorite games with 160 points on us." As you can see, the box says "Sorry, the code is no longer available." I clicked the link "Redeem Now" and didn't get any points on my account. It said to enter a 25 digit code, which I don't have.
Text of the email says: "You want more from your favorite games. You can get it with Microsoft(R) Points. And we're giving you 160 free points right now.* Just redeem the code below to get your points: Then head to Xbox LIVE(R) Marketplace and use your points to get game add-ons, Avatar gear, Arcade games, movies, and more. "
The sender is *** Email address is removed for privacy *** and the links go to click.engage.xbox.com.
Please tell me how to get my 25 digit code for 160 points.
