Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi Matt
If it's a Microsoft 365/Teams business trial, try going to Microsoft 365 Admin Center> Billing > Your products, select the subscription, and look for Cancel subscription or the recurring billing settings.
If you've already checked there and still don't see a Cancel subscription option or recurring billing settings, I'd recommend contacting Microsoft Support directly. Subscription and billing information is specific to your tenant, and forum members don't have access to those details to investigate why the cancellation option is unavailable.
To summit support ticket to Microsooft support team, youi can go to the Microsoft 365 Admin Center > Select the Help & support (headset) icon. If Support Assistant is enabled, turn it off > Type contact support in the search box > Select Contact support, then choose Phone or Email to submit your request.
For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.
I hope this information helps.
