Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello
When you check the subscription section in your account did you end up with two subscriptions? If so cancel one of them and contact support to sort out the billing issue. That cannot be done on a community forum.
Go to https://support.microsoft.com/contactus, Type "Billing" and press Enter. On the next screen, click "Contact support" at the bottom of the page, then choose "Microsoft 365" > "Manage my subscription". You’ll then see the option to chat with a Microsoft support agent who has access to your account to help review the issue.
