microsoft won’t send me a new password

Hi,

Hotmail wasn't working for 2 days so I though someone might have hacked it. So I changed my password , nothing changed , so I then changed my username , then my email address ( I soooooo regret it now!!!!!).
But then impossible to log in , the password won't work.
I have been sending forms after forms to microsoft with as many details as I could but they kept on replying that it wasn't enough , until the last one they told me I just had to open a new account !

I am a homeschooling mum , I have all my children's tests, grades  on my hotmail  , I really need to have it back .
I have beem giving so many information about adress email, names of folders, the facts that I never write subjects, the last emails I sent to whom....that's a lot of information , I don't understand why this is not enough.
 

my original hotmail adress was
*** Email address is removed for privacy ***
pass. ramada10

I changed it to
*** Email address is removed for privacy ***  ( this mean , I am fed up...you see the frustration)
pass. dieuaidemoi             ( this mean God help me hahah)

my file number is 51484844.

Thank you for your help
