it looks like someone might be using your account — PLEASE HELP URGENT!!

I'm having trouble with my other Microsoft account.. everytime i want to login "it looks like someone might be using your account" appears.

Unfortunately my alternative account has been disabled long ago so i'm forced to fill some kind of questionnaire about my blocked account.. i've already filled this questionnaire so many times and i can never get through my account. My social app such as instagram is connected to this email and i have some important email in this account i have to review..

Somehow i can't sign in to my instagram account and it is not linked to my facebook so i have reset my password which is the email that's connected and the one that can make me go through instagram account again is this my other hotmail account, i have to make another account to start this discussion.. i'm microsoft client from indonesia from i can't remember when.. hotmail is my first email account.. 

I'm also a graphic designer.. my portfolio is in my instagram and i have to access it to be able to work.. that's why this is very important to me

Please, i beg of you Microsoft Team.. Help me..

Thank you so much!
