“I need help with a duplicate Microsoft 365 Personal charge. Bank of America confirms two $99.99 payments went through. I need the duplicate $99.99 refunded without canceling my active subscription.”

Hello,

This is a public forum, so for your privacy and security, we can’t help with billing issues here. Also, no one in this forum has access to your account or payment information.

To get help, open the "Get Help" app on your computer (just search for it in the Start menu). or 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.
