Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello, good day and thanks for your question. In this scenario, it is best to update your information first via https://go.microsoft.com/fwlink/?linkid=2195908 and this also includes changing the country and then add the card that you will be using via https://account.microsoft.com/billing/payments. As you have an existing subscription, you will need to cancel it first before subscribing again and then you can go to https://account.microsoft.com/services/microsoft365/billing and try it from there or try to turn off the recurring billing at https://go.microsoft.com/fwlink/?linkid=2277073 and you can also follow the guided steps indicated from the link below.
You can also request a call back by going to https://go.microsoft.com/fwlink/?linkid=2168171 in case you are having trouble cancelling or you have encountered any other issue.
