Locked out of my account - Request rejected

My account got hacked by a spam bot a few weeks ago and as a result my account was locked. I have tried to get a code sent to my phone to unlock it but no code is sent despite it being the correct number as far as I can see.

Since then I sent a request to the hotmail team with the information about the account that I had but it has been rejected twice. I can't remember the answer to my security question because I created my own question about ten years ago.

I literally have no more information to give. What can I do?

Here is the email I received back from hotmail:

'We recently received a request to recover your Microsoft account ******@hotmail.com. Unfortunately, our automated system has determined that the information you provided was not sufficient for us to validate your account ownership.  Microsoft takes the security and privacy of our customers very seriously, and our commitment to protecting your personal information requires that we take the utmost care in ensuring that you are the account owner.'

Thanks
