Hi @Mohammad Yadak ,
Thanks for using Microsoft product and posting in the Microsoft Q&A.
I'm sorry to hear you're locked out of your account. I understand how frustrating it is to be stuck in this loop, especially after trying so many different methods.
Unfortunately, as a community support agent, I don't have the tools or authority to directly access your account, bypass security settings, or investigate issues with OTP delivery. This is for your own security, as we need to ensure that only you can make changes to your account.
The best and most secure way to recover your account is through the official automated process. Please visit the Microsoft account recovery form and provide as much information as you can. The more details you can provide, the higher your chance of a successful recovery.
Additionally, let's look at a potential cause for the SMS issue. Could you tell me if the registered phone number is a Voice over IP (VoIP) number? Microsoft's systems are unable to send verification codes to these types of numbers, so that might be why you're not receiving the OTP.
In the meantime, you might also want to check with your mobile service provider to ensure there are no blocks on receiving SMS from short codes or international numbers, as this can sometimes be the cause of delivery issues.
I know this isn't the quick fix you were hoping for, but these steps are your best path forward for a secure account recovery.
Please let me know how these suggestions work for you, or if you'd like assistance in navigating Microsoft's support channels.
Warm regards
Chloe L. | Microsoft Q&A Support Specialist
