Hello Nixon Zepeda, Thanks for using Microsoft products and posting in the community. I am aware of the present situation is that you are encountering the challenges of getting charged for a Microsoft 365 subscription that you did not mean to have, and you want to stop it. This could be the result of automatic billing. Kindly refer to this article - < Turn recurring billing on or off for Microsoft 365 for home - Microsoft Support> 

There are two privacy guidelines restrict community support for now:

• Privacy and Security: Financial and subscription issues often involve sensitive personal information that should not be shared publicly on forums.
• Access account information: Community agents do not have direct access to users' subscription details or billing information. Therefore, we are unable to verify payments or make changes to your accounts. This information should be left to Chat support and be in an individual window

You can contact our online support by following the steps below and they will be able to assist you:

1. Visit this website: https://support.microsoft.com/en-us/home/contact
2. Type in your problems in the search box there. For instance, subscription/Tax invoices/refund, etc.
3. Now click Get help, and Select Contact Support below.
4. Go to the Products and services tab, and choose either Microsoft 365 and Office category or Other Products
5. On the Category tab, choose Manage My Subscription or other alternatives.
6. Go to Confirm.
7. You can now choose the option of Chat with a support agent on your web browser.

Please Note: The Chat support team only works at certain times, so if the last window says you are not available, try to open it again the next day. If you prefer phone support, you can leave a phone number. That way, they can call you and help you.
