Unable to acquire Office 365 A1 Education – Error 43881, billing account inactive (tenant created without trial)

Question

Hello,

I am the IT administrator of a Catholic school in Poland (Zespół Szkół Stowarzyszenia Rodzin Katolickich, Wodzisław Śląski). I am experiencing the exact same issue described in question #5701983 (Anh Le, January 2026).

SITUATION:

• Tenant: zespolszkolsrk.onmicrosoft.com
• Custom domain: katolik-wodzislaw.edu.pl (verified, .edu.pl extension)
• During registration at microsoft.com/education, error 43881 occurred
• Tenant was created successfully but Office 365 A1 trial was NOT added
• Academic eligibility verification status: "In progress" (banner visible in admin center) — will never complete without the trial subscription
• Billing account status: appears Inactive (0 products, A1 not visible in Purchase services)

WHAT I HAVE TRIED:

1. microsoft.com/education → "Get started free" → error: "Contact your IT department to get a license"
2. Direct signup URLs with A1 SKU GUIDs → error 43881
3. Microsoft support phone (225941000) → redirected to email
4. Email to lbywar03@microsoft.com → redirected to chat support
5. Chat support → generic bot responses, no resolution
6. Email to msedu@microsoft.com → bounce (address does not exist)
7. Services Hub → redirects to Admin Center chatbot (loops)
8. Admin Center support → chatbot loop, no human agent available

WHAT I NEED:

Escalation to Microsoft Commerce Department to activate the billing account on backend and provision Office 365 A1 for Faculty subscription — exactly as was done for Anh Le (question #5701983, resolved 2026-01-23).

No tenant recreation required. The domain and tenant are correctly Microsoft 365 and Officeconfigured (DNS verified, TXT record added).

Tenant ID can be provided via private message.

Thank you.

Update: The only answer received so far was AI-generated and has been rejected. All support channels listed in that answer have already been exhausted prior to posting here — they either loop back to the chatbot, bounce (msedu@microsoft.com), or redirect to non-existent phone numbers. Requesting escalation to a human Microsoft moderator. Direct precedent: question #5701983 (Anh Le, resolved 2026-01-23 by Microsoft Commerce Department backend fix — no tenant recreation required).
