Hello FayezPK,
Welcome to Microsoft Community.
We are sorry to learn that your Microsoft account has been compromised by a hacker, and I recommend that you visit the following support link as a priority and follow the instructions in trying to restore your Microsoft account:
How to recover a hacked or compromised Microsoft account - Microsoft Support
But I notice that you have tried several times the last option we can give, which is to fill out the recovery form, but you have not received any reply emails. My guess is that the hacker may have changed the email address associated with your account and blocked all channels to retrieve your account, which makes it such a difficult task.
I understand your frustration, but I'm sorry, there's nothing we can do about it.
Create a new account to use, and try to keep all the information related to the account, including email, mobile phone number, authenticator, password, and so on
Best Regards,
Mitchell | Microsoft Community Support Specialist
Then what about the money that I have spent on it?
