Wrong points

Hello PlanBacon,

From the FAQ for that offer:

How do I earn Rewards with this offer?

Share the Digital Rewards lets you earn Rewards Credits by referring your friends to make their first digital purchase of Xbox One or Xbox 360 content.
You'll receive 5,000 Rewards Credits for each friend you refer who spends at least $25 before tax on Xbox One or Xbox 360 content in the Xbox Store or Microsoft Movies & TV, and we’ll give your friend 5,000 Rewards Credits, too.
To get your Reward, they just have to make their first purchase within 30 days of your referral.

Since one of your friends recently completed this offer, the Credits for that successful referral are now in your account. You both got 5000 Credits! You may have confused our refer a friend to Gold status offer with this offer.

Hello Dark0Energy,

Since you did not complete 5 achievements for your purchased items, you did not get the Credits for achievements or the bonus for full completion of the offer.

it was a glitch in the system. the points that were not yours should have disappeared; i know i had 2190 on my account and then when i looked two hours ago they were all gone; i'm assuming it's been fixed since mine had disappeared. (I called phone support
and they informed me of what happened)

Yep, excess point had disapeared and now I have exactly 4220 points.

I would guess that the 220 was from rewards. And I read an article online that says their has been a glitch going around adding free points to accounts. Cannot 100% confirm that since I cannot find the article anymore.
