SVC-RedeemServiceUnavailable

Hi there,

Remeeming errors can be caused by issues on the account itself. Be sure to check if your billing information is correct at
http://billing.microsoft.com and also check
http://account.microsoft.com/services for any outstanding amount issues, these need to be sorted prior to being able to redeem codes.

After that try redeeming the code on both xbox console and via xbox.com/redeemcode

Also check that the Xbox Live account , the console and code all match region wise, using different regions for any of them cause issues too.

If you can't find anything wrong and it is still not working, best thing to do is to contact official Xbox Support via Phone or Microsoft Support Chat at
http://support.xbox.com/contact-us they can do a more indepth look into this issue.

Credit cards can't be copied from any account including your bank account the numbers are hidden and the security code is not visible anywhere but the card itself

They would need access to your actual card Validation would fail and your bank will reject any transaction without the svc You can ask your bank what it takes to add an card to an account Svc and complete creditcard number and name and billing address All online
vendor and stores require entering the svc Or in most of the world using a chip card at store or using svc for online

So the point is

I kept getting an error on the xbox site:

Try that again
Something happened on our end. Waiting a bit might help.

SVC-AuthenticationTokenInvalid

And then I found out it's impossible to contact them if you don't count that one "agent" sitting by the phone on antarctica

Hi, what did cust svc say?

Ask your bank for another card and the svc and the old card will be invalid
