i need help for microsoft rewards

The Microsoft Rewards pogram is not changing. The Xbox Rewards program is turning into the Microsoft Rewards program. So you would not lose any Microsoft Rewards points.

If you need further help with the Microsoft Rewards program, you would need to contact their customer support via their redemption page.

If you need further help with the Xbox Rewards program, you would need to post in the Xbox Rewards Questions support forum.

Unfortunately you can only earn these points if you purchase and Xbox one S console from the Microsoft On-line Store. You earn points for every dollar you spend with Microsoft.

It usually takes a few hours but if not contact support

Hopefully you activated the punchcard before you purchased the game !

If not, there is no chance to get the points.

If yes it could take longer than some hours, because they don't want to give away points and then someone is requesting a refund ... ^^

That promotion is for the Microsoft Rewards program, not the Xbox Rewards program. For help with the Microsoft Rewards program, you would need to contact their customer support via their redemption page.
