Microsoft project management software used to plan, manage, and communicate a project schedule and other information among workgroup members, project managers, and other stakeholders.
Thank you for providing these details. I understand that you have been attempting to cancel this subscription since August 2025, but have been unable to do so because you no longer have access to the work account that may be associated with the subscription. As a result, the subscription has continued to renew and charges have continued to be applied even though you are no longer using the service.
I also understand that you have already contacted Microsoft support channels multiple times, including chat support, without obtaining a resolution, and that your bank has since reversed several charges, which has now resulted in overdue invoice notifications from Microsoft.
Unfortunately, subscription cancellations, billing reviews, account ownership verification, and refund requests are not something that can be resolved through the community forums. These actions require access to Microsoft's account and billing systems.
To help move this forward, please follow this link to create a trial tenant: https://www.microsoft.com/en-us/microsoft-365/business/microsoft-365-business-basic?msockid=3eb6980b5c6860e63a588d0c5d1761d6 - after that you will be able to access to Microsoft 365 Admin Center to raise the ticket
Assuming that you have already created an account after registering a free trial and you can go to Microsoft 365 admin center and click "Help & support" icon to raise your ticket. The agent will be able to create a ticket for you under the affected tenant and then transfer this ticket to Data Protection team who could help you to regain access.
Please mention that you are raising ticket on behalf of the affected tenant that you do not have access to. The support team will help you to create ticket on the affected tenant then later on the Microsoft Data Protection team will assist you.
Note: This process will take more time than usual (7-14 working days) for your account to get access again as Data Protection is always overwhelmed with the number of tickets. As I am user, I do not have access to Microsoft internal system to assist or push this process to be quicker.
On the other hand, if you do create the trial and it resolves the issue, please remember to cancel the subscription afterward to avoid any related charges.
I hope my information is helpful. Please give me any updates once you get this resolved.
