Dear Osama Ali,
Thank you for following up regarding the difficulty in reaching Microsoft Business Billing Support. Business-related charges such as the one described are handled by the dedicated billing team, and the most effective way to connect with them is through the Microsoft Business Support portal. When the automated system does not recognize a subscription, providing the transaction reference number (24204296060000405454211) and the card details ending in 3852 is essential. This information allows the billing team to trace the charge even if it is not linked to your visible accounts. If the online form blocks progress, the recommended approach is to use the “Contact Support” option within the Microsoft 365 Admin Center or request a callback by entering the transaction details directly. This ensures that a billing specialist can review the case and provide assistance in stopping future charges.
