Cannot Pay Past Due MS Cloud Balance in Portal - Service Deprovisioning Today. Need Direct Support Channel.

I have an urgent issue with a past-due balance for my Microsoft Cloud services (Billing Profile: VRAI We Are AI). Our account has received a warning that services will be deprovisioned and data deleted TODAY.

I am trying to settle the full amount of $56.93 USD but am encountering an issue that prevents me from completing the payment directly through the billing portal.

Details of the Issue:

Total Past Due: $56.93 USD

Urgency: Deprovisioning/data deletion scheduled for today (November 26, 2025).

Invoices: G106566704 ($35.60 USD) and G112089778 ($21.33 USD).

Problem: When attempting to pay the outstanding balance, the portal either gives an error, fails to process the payment, or directs me to "Contact Support" instead of completing the transaction. (If you see a specific error message, include it here).

I am unable to resolve this via the standard online payment flow and must process the payment immediately to maintain service continuity.

Request:

As this is a critical, time-sensitive billing issue, I need the fastest possible way to reach a Microsoft Billing Specialist who can manually take the payment or provide a secure alternative payment link.

Can a moderator or expert please confirm the most direct and fastest support channel (Phone number/P-1 Support link) for this specific scenario where a customer is blocked from paying their past-due balance in the Admin Center?
