Hotmail Password doesn’t work and no word from windows Live Help in over 48 hours

Hotmail started saying that I was using the incorrect password.  Since I created my account over 15 years ago, the mobile number is old and the security question, at that time was created to be a reminder for my password, so therefore it doesn't work.  I have been on the online chat and given the validation form to fill out and my reference ID is 1213597554 and told that someone would get back to me in 48 hours which hasn't happened.  I'm getting very anxious because I'm due to fly in a few days and the details are in the email account.  No one is able to provide any information.  I can't talk to anyone.  There isn't even an official platform to lodge a complaint.  I want to know what hotmail is going to do if I miss my flight.  I can't believe that it takes this long to recover an account.  What can I do to expediate this matter!?????

If recovering an account is this complicated, then I don't understand why hotmail doesn't force us to update our information every 6 months when we log on.  Surely after all the people on this forum have been long time users suddenly locked out and not remembering their information from over 10 years ago, I'd think that hotmail would come up with much easier ways to recover accounts and verify owners.
