    Thanks for reaching out, and I'm sorry you're running into this issue.

    The error code 43881 typically points to a payment method verification issue, even when the product is listed at £0.00. This can happen if the system is unable to validate your card details or if there's a mismatch in account or licensing setup.

    Since the support number you were given isn’t working, I recommend opening a support ticket online to get direct assistance:

    Microsoft Nonprofit Support Portal: 

    • Go to https://nonprofit.microsoft.com/en-us/getting-started
    • Click on tab to contact someone in the top banner
    • Once you're on the page:
      •     Type “support” in the “How can we help?” box
      •     Fill out the required fields
      •     For “I am a…”, select “Current Nonprofit Customer”
      •     For “What can we help with?”, choose “Nonprofit Offerings”

      This should route your request to the appropriate team who can help resolve the error and complete your license claim.
