Recovering my old Hotmail account

Greetings!

I need help to recover an old Hotmail account!
Unfortunately, and to my surprise, I can't remember the password, nor my security answer.
I only set up the account to go along with an account on Blizzard gaming, which I am trying to get back on to, and they informed me that this forgotten email address of mine is actually the one that they have on record.

I can provide all the information about the account, but not enough in order to fill in the account recovery form.
This is because, to my best knowledge, I didn't use the account to write emails, nor did I make folders, and there are no Xbox membership or credit card detail associated with the account.

What should I do? What options do I have?
I need access to this email in order to recover my Blizzard account, but I'm at a loss as what steps to take.

Also, I am given the option to be contacted my text or call to recover the password, but the last two digits of the phone number (as they are shown) are not familiar to me.
It's frightening how much someone can forget by not using an account for so long.

Please, help me!
