Hi,
Please check if you have an option to change your account security verification method if you do not have any other method available.
On the verification page, choose “I don’t have any of those.” This will begin the process of adding a new verification method.
Please note that updating your contact information requires a 30-day waiting period. I know this can be frustrating. This waiting time is a key part of Microsoft's security measures. It helps protect your account in case someone tries to change your contact details without your permission. While I understand it may be inconvenient, it’s designed to keep your personal information safe.
If you do not have this option, you need to wait for the response from Microsoft support to assist you further with your recovery. Sometimes, they may take a while to respond due to high request volume.
If you required addidtional assistance, please let me know.
Stay Safe!
