Updated billing

Hello ivorplayedallot,

We responded to your post at (https://forums.xbox.com/en-US/thread/56e180ed-1dd2-4143-8ccb-a7a6e9565892) regarding why this deposit is failing. Unfortunately, we have
still not yet received a resolution from the other team working on this issue. Again, apologies for the inconvenience.

Hello GruffleGrinder,

There is currently an internal issue with the data stored for your account which is preventing a deposit. Our deposit process cannot correctly determine the primary billable account to deposit into for your Microsoft Account, and thus aborts the process.
This is an issue that we are working on resolving with another team, since we are not able to fully access the database containing billable account information. At the moment, we have not received a estimate on when this problem will be resolved. To be clear,
this is a data issue, and not the result of any faulty user input, so adjusting your information will likely not solve this issue. We apologize for the inconvenience.

Hello

Where you can get more help

Hello Kroobz,

After reviewing your account, it appears that you are currently being affected by a known internal database issue which is interfering with the information on your account. What is happening is that your billable account information is being incorrectly
communicated to our servers. Since this data is necessary to determine where to place your deposit, the process is aborted. This missing information is also why our system is incorrectly asking you to update your data. This issue is currently being worked
on by another team. At the current point in time, they have not yet provided us with an approximate solution date. We apologize for the inconvenience, and ask for your patience while our other team works on a solution.

Having no ability to change payment methods hardly renders console useless.

It's not clear if you're using console or pc to attempt, so as others have suggested, try Account website

Next, check that live service is having no issues, which can be done Here as I know that there have been a few issues with purchases in the last few days.
