Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I have exactly the same problem. It has been REALLY frustrating trying to get in touch with MS about this. I started using online chat with them and initiated a conversation at 12.14 BST - I was informed that I was 903 in the queue. After nearly 2 hours that has now dropped to 699 !!!! This page and the service status message have given me the information that I require. I only wish I could have found it all sooner.
