Have not recieved my Reward Credits from my Purchase.

If you're referring to the offer to receive 15,000 credits for preordering a game, keep in mind that the credits should show as pending about 10-15 business days after the game ships as long as you preordered from microsoftstore.com. If it's been over that,
or you're referring to a different offer, you'll want to post in the Xbox Rewards Questions forum so support can check for you.

Hi, for rewards related questions, I would advise posting this in the Xbox Rewards support forum instead -https://forums.xbox.com/xbox_support/xbox_rewards_support/default.aspx

Keep losing your customers because you have no customer service, your choice.

For help with the Rewards program, you'll want to post in the Xbox Rewards Questions support forum. If you can post any of the offers you're looking for credits from, that will help.

Hello RoundWorm503,

You can earn Xbox Live Rewards Credit in two ways:

1. By finishing the offers located on the MyMissions page at
https://rewards.xbox.com/mymissions/ .

-or-

2. For non-offer purchases, you can earn Credits by earning a one star MyVIP level through purchasing at least $300 USD or regional equivalent of eligible content. After you receive your first star you will begin to earn a percentage of your eligible purchases
back as payback Rewards Credit. Pre-orders, in-game consumables, and subscriptions are not eligible for MyVIP.

MyVIP has a recalibration every year. At the end of the year, we place you in your MyVIP rank for the new year based off your eligible spending from the previous year, and set your progress to the default state. This happened in September 2015 and December
2016. Since you are a zero star member, you do not get payback Credits on your purchases. You can check your current MyVIP level/progress at (https://rewards.xbox.com/myrewards/).
