xbox error code 80154058

What's error 80154058 when i try register my offline account with my xbox 360?

That code appears when trying to buy, since the issue is with a redeem code, better to contact official xbox support, use the Phone or Microsoft Support Chat option at
http://support.xbox.com/contact-us because could have some issue with the code, and they can find that

What are you doing when you get this error? Making a purchase, loading a game?

Hi CMDRrecks,

You can always check the status of Xbox Live here to see if there are any alerts https://support.xbox.com/en-US/xbox-live-status. Are you seeing this code on
your Xbox 360 or Xbox One.

Hello Magicdolphin4!

Have you tried other methods of redeeming the code?

If it doesn't work when you try it on the console, then try on online within payment and billing in your account.

There should be a button called payment options that you should be able to redeem the code through as well.

If it doesn't work either online or on the console, then yeah, your best bet for resolution of this issue would be to contact support as previously mentioned.

Let us know how that helps with the issue

Much thanks!
