Cannot access my account after code from Authenticator App does not work after I change my mobile

Dear all,

I have been trying to access Microsoft Support, the problem is I cannot login because of code cannot verified from my Authenticator App after I change my mobile. I am asking if there is a way for me to contact a real huan support in Microsoft because right now, the call, the support chat is all control by AI, and the cannot answer my request to disable my Authenticator App.

I have nowhere to turn as I cannot find any answer to this problem in web, and their move to change all support into AI ether from call or chat make it worse
