Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi David! My name is Ben a fellow member in the community like you and hope you are well!
With regards to this issue when you are trying to renew your Microsoft 365 subscription. Can you share with us what error message you are seeing when trying to make a payment?
In the meantime, please also check the billing address on your Microsoft account and make sure it is correct or matches the one on your card. You can check and update it here:
https://account.microsoft.com/billing/payments
Also, please try using a different browser or device and see if that will allow you to make a payment.
Don't hesitate to post back here if you have other questions and we'll try our best to help.
