Rewards aren't showing up for MyVIP?

Support will double check it, but make sure you're checking your rebates on your statement on the MyRewards section of the site, not the MyVIP page. VIP rebates would be listed as credits earned on the last day of the month they are for.

Hi Princesskit10. The award you see is for completing the First Purchase offer. To earn payback on your purchases, you need to have a Star Rank. You currently are 84% on your way to unlocking a Star Level. Your current eligible purchase amount is $254. To
see what purchases qualify for MyVIP, check out our
FAQ.

Rebates are calculated after the end of the month and given by the 15th of the next month. So it's too early to see credits pending for November purchases.

Same here,3 days later and mine still aren't showing up on Microsoft rewards

Hello TOXIC2theHEAD,

From the transition FAQ:

What will happen to my Xbox Live Rewards MyVIP Gems, MyVIP Perks, and MyVIP Vault?

You’ll have until May 31, 2018 to earn MyVIP Gems and unlock any new MyVIP Perks. You’ll then have until June 15, 2018 to claim any open MyVIP Perks and to redeem any unused MyVIP Gems in your Xbox Live Rewards account for prizes from the MyVIP Vault. After
this date any unredeemed MyVIP Gems will be converted to Microsoft Rewards points and can be used to redeem rewards from the Microsoft Rewards catalog once your membership is transitioned. One MyVIP Gem will convert to one Microsoft Rewards point.

Your 556 Gems will be converted to Microsoft Rewards Points when you are fully transitioned into Microsoft Rewards.
