Were they both in your Microsoft account? Or did you pay via Microsoft once, but another directly from Adobe?
If they are both in your Microsoft account, 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 "Windows" > "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.
You can reference this detail step by step instruction with screenshots I posted in this thread: https://learn.microsoft.com/en-us/answers/c/2714817
==========
If you have one via Msft and one via Adobe, you will need to decide which one to keep and which one to cancel, and then contact accordingly, either Microsoft or Adobe to cancel one of them.
