Trouble processing payment

I'm not sure if it was the same error code, but about a year ago I had a similar message when trying to purchase a game which said that it was having trouble processing my payment. I knew there was no issue with my debit card, so I wasn't sure what
was causing it either. I wound up backing out of the Store and left it alone until later that evening. Then I tried again, a few hours later, and it went through fine. Just thought I'd add this, in case you might want to try again and see if it does go through.
Good luck!

Yes the same thing happened to me think the servers are being taxed this week

Hey there JackVossler,

Thanks for reaching out to the Forums for advice on how to deal with this issue. I can totally see how getting this error could be pretty frustrating. Since it straight up says to contact support, I suggest
contacting support as there could be something that is messing everything up.

When you get the chance, give that a shot and let us know if that helped.

Thanks!

Since this is a billing and refund related issue, you will need to contact Xbox Support directly here-

Don't forget to explain your situation and they will be able to help you

Think it's a server issue it's a bit common

Gamertag changes require a credit card to be on file. That's why the payment process won't complete.
