Hi @Kaysha Wilson
Thank you for posting your question in the Microsoft Q&A forum.
It sounds like you've already tried the official support channels and are stuck in a frustrating loop. Unfortunately, Microsoft doesn't offer a direct email address for billing issues, but here are a few steps that might help resolve the payment issue:
1.Cached sessions can sometimes interfere with payment processing. Try signing in to the Microsoft 365 admin center using a private/incognito window.
-Go to Billing > Payment methods and confirm the new card is active and set as default.
-Then, navigate to Billing > Bills & payments > Select the overdue invoice and click Pay your balance.
-If the payment fails again, take note of any error code that appears, it can help support diagnose the issue.
2.Try submitting a support request in the Microsoft 365 Admin Center a different browser, it often bypasses redirect issues.
3.If your issue still persists, you may try the Microsoft 365 Admin mobile app. The mobile app often bypasses the redirect problem seen on desktop.
Download the app (iOS/Android) > Sign in with your admin account > Go to Support > New service request > Type "billing" > Contact Support.
I hope this helps.
