Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Stauffer,
Thank you for reaching out, and I’m sorry the current support process has been so unhelpful. Being sent back and forth between the admin center and the Contact Us page is understandably inconvenient.
You can create a support ticket directly in the Microsoft 365 admin center by selecting Help & support and submitting a service request. Microsoft Support can then investigate why the payment notifications continue after your billing information was updated.
For guidance on how to request support in the admin center, please refer to: Get support - Microsoft 365 admin.
You may also find the appropriate Microsoft phone-support number for your region here: Customer service phone numbers - Microsoft Support
When opening the ticket or calling support, include your subscription details and copies of the emails.
I hope your issue gets resolved soon. Any updates would be greatly appreciated.
