Account Recovery Request

I've been trying to recover my hotmail.com email address.
I was able to reset the password using my mobile number.
But when I sign in again, it is blocked again.
When I try to recover using my mobile number: (Try another verification method. That verification method isn't working right now. Please try another method.)
I submitted 3 recovery forms already but were unsuccessful.
My hotmail.com account is only being used as a receiving email address of important bank emails.
I don't remember sending any email.

I need help to call or chat with support.
