Received an email stating
|We attempted to deposit your Rewards Credits into your Xbox Live account, but we encountered an error. To fix this, we need you to take the following steps:|
|1. Go to Microsoft Billing.|
|2. Make sure your account information (including country and region) is correct.|
|3. If you're still experiencing problems, make a post to the Xbox Forums.|
All of my information is correct and up to date. I contact Microsoft Support already after reading other forum posts and they just told me to post here.
