Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello, good day and thanks for your question. To add to the above, you can also check and test this on a different browser and to also try inPrivate or Incognito mode. Another alternative is to link your card to PayPal and then use it as the payment method to pay for the subscription. If you will still encounter an issue after checking and trying these, you can reach out to the support team at https://support.microsoft.com/en-us/contactus/ and then click on Microsoft 365 and then click Get Home Support and then type in Billing question and click the blue button that says Sign in to contact Support and login and proceed from there and kindly take note that the forum does not have access to user accounts to be able to check this billing side of things. https://support.microsoft.com/en-us/account-billing/add-a-new-bank-or-credit-card-to-your-microsoft-account-c39dbc30-bc83-30c8-5ea9-d0d94e6dcfe4
