Hi @Joel Muhoza,
Welcome to Microsoft Q&A forum.
Thank you for reaching out and for the detailed information you’ve already shared. I understand how disruptive it can be to encounter payment issues, especially after confirming with your bank that there are no problems on their end. I appreciate your patience while working through this.
Based on what you described, card declines can sometimes occur due to automated security checks, regional or merchant-specific restrictions, or temporary authorization issues on the payment processor’s side, even when sufficient funds are available and the bank reports no errors. Unfortunately, these declines may not always provide a specific reason that we can see or override directly.
As a temporary workaround to help you complete the Microsoft 365 purchase without further delay, I recommend trying a different card if one is available (for example, another debit or credit card). Once your subscription is active, you can usually update the payment method later if you prefer to switch back to your original card. If the issue continues even with another card, please let me know and I’ll be more than happy to explore additional options or next steps with you.
I hope this information is helpful. If you have any questions or need additional assistance, please don’t hesitate to reach out so I can continue to support you.
Thank you for your patience and your understanding. Wishing you a great day ahead.
