MCA billing account stuck in "under review" status for 4+ days, no resolution

I'm the Global Admin for a Microsoft 365 tenant (domain: fortunamg.net) recently transitioned from a GoDaddy CSP reseller relationship to a direct Microsoft Customer Agreement (MCA) billing account.

After setting up the MCA billing account and adding a payment method, I attempted to make an edit to my billing account address (updating to the new 9-digit zip code format). This triggered an "Account under review" status, which states the review usually takes up to 2 days. It has now been over 4 days with no update or email notification.

This review is blocking me from purchasing a subscription, which I need to do to restore an active Microsoft 365 subscription on this tenant (currently showing as "Disabled" following the GoDaddy detach).

Billing Account ID: 7793dd6e-68c9-5362-c5e2-3fe091b9854c

Domain: fortunamg.net

Could someone help check the status of this review or escalate to the appropriate team? Phone support has been unable to resolve this. Thank you.
