Never received $50 promo card

You would need to contact customer support for microsoftstore.com since that offer would have been through them.

Thanks Darkplayer 2. I am looking to buy the Xbox gift card from an online vendor, like NewEgg, Amazon, etc... Which they occasionally have promo codes that will discount the Xbox gift card by 20%. So the $50 gift card would only cost me $40 after the
promo code.

This is good to know, b/c one review I read somewhere said the $50 card does not cover the everything and they could not split the transaction to cover the tax.

This happened to me as well. Received only $5 promo card after purchasing a year renewal!

Sorry, but you got scammed. Feel free to send in your info, but you'll only spend hours on the phone and learn just this: If you call before the 8-10 weeks is up, the reps tell you that they can't tell you anything about when you might receive it and to
just call after the 10 weeks if you haven't received it. When you call after the 10 weeks are up, they tell you that you should have called more often and that since you didn't you forfeited your right to receive the game. If you keep pressing them, they'll
tell you that the offer is expired and that Microsoft does not have any more copies of any of the games for the promotion. If you ask them for a digital copy of the game, or for a refund of XBox Live, they will refuse. They don't mind spending 3 hours on
the phone over 5 different calls, but they definitely mind living up to their side of the bargain.

I know, I've been through all this. Here's what I finally told the representative, and what I plan to do- I refuse to renew XBox Live from this point on. I refuse to purchase any materials from the XBox Live Marketplace. I will buy all games used from
this point on, because I know how this impacts their profit. And I will blog about this experience in half a dozen places. XBox will lose a couple thousand in revenue just from me, as I have a lot of people on my Christmas list and buy about 20 games a year.
And I'm hoping that others will follow my example, and that such short sighted business practices will be justly rewarded.

Thanks Lofedog! I've sent you a PM with some more information. Thanks!
