There is not anyone in this open forum who can help you with the specific issue of yours. You must contact MS support. When filling out forms like the one you refer to, you must be exactly accurate.
Usually, the recipient's email address and
accurate text of message heading are needed. This is necessary so that the
check can be done by machine.
What was the reason for your being locked out from your account? Here are some ideas that might help you
Procedures for password recovery / account recovery.
The reasons for the recovery can be several: Forgotten password or Microsoft has locked the account
for some reason.
Important:
If an account is not accessed for one year, the account becomes inactive and all emails are deleted. The account can only be recovered if you know the
address and password.
If you have not accessed the account for two years, the account is permanently closed. Recovery is not possible and the address cannot be used as an
alias or to create a new account.
Restoring a password or account normally requires that you have created security information for
your account that allows Microsoft to verify the account holder. E.g. mobile number and other email address for receiving verification code.
If such information is missing, you must fill in forms that prove your ownership. In addition
to personal data, information from one's email conversation may be required. Do you have access to it e.g. via mobile, where logout is usually not done, it is an advantage. If not, contact some people and ask for help. Usually, the recipient's email address
and accurate text of message heading are needed. This is necessary so that the
check can be done by machine.
Another way is to reset the account on your own, which assumes that a recovery code has been generated.
In summary, it is
important that you plan for a recovery when the account is created.
Resetting the password is usually easier to recover from than resetting the account. In
the first case, the account opens automatically after a certain time.
Reset password if it is forgotten
Go to sign into your account:
https://account.microsoft.com/account
Select Forgot your password?
Do you have recovery information to receive verification code?
Do you have an account recovery code (25 characters)? (See also Recover account).
If you have been able to use any of the options above, the reset will be undramatic.
If you do not have any of those, you must enter a temporary email address that is immediately available to you,
for the continuation of the recovery process.

Open a locked account
The locking can be caused by unsuccessful password reset, failed login verification or questionable activity
on account. Please note that it might be possible to use EMAIL even though the account is quarantined i.e. you are already logged in.

To unlock your account, you must enter a security code you receive via text message
from Microsoft. The phone number you use to receive this text message doesn't need to be associated with your account. It doesn't even need to be your own phone number. If your phone doesn't receive text messages, ask a friend or family member if you
can use theirs. Microsoft won't save this phone number.
If you see a "usage limit exceeded" error message when requesting a security code,
this could mean the phone number has been used too many times in a short period of time, or that we've detected something suspicious about the phone number.
Then use a different number.
Recover account

When you reset your account, the old verification information will be deleted, and you will need to enter a new
(albeit temporary) email address that was not previously associated with the account. New reset code is generated, and two-step verification must be re-enabled. Once you re-enter your account, you can revert your old verification information.
Change password and / or security information
Should be done immediately if it is not already done.
Sign into your account:
https://account.microsoft.com/account
Change Password
Supplement your security information to receive a message or verification code from Microsoft:
Email account, Mobile number, Fixed phone number.
Enable 2-step verification
Create an account recovery code (25 characters)
