I am having an issue with my account, I recently bought a DLC for a game and now that I got a gift card for Christmas I deleted the previous card on my Xbox and now I cannot add a new one. Even when I go online and try to click the Add credit card option the link will not follow. I noticed it would not work when I entered my gift card (It's a master card prepaid) the expiration date was 2021 and I put it as 2020 for that was as high as it would go and now I cannot even add a card on my computer. Is something wrong or is it closed for Christmas?
In short: I cannot add a credit card and the links to do so will not work.
