Microsoft store help

Hello,

I can´t use my Microsoft account.

I don´t know the person that is associated with the unknown Email.

The only thing I know is that their email is ******@163.com

Whenever I want to log in to the microsoft in, I need to verify via the unknown email which I neihter posses nor know.

I really need help because I just can´t unlink my account with theirs and therefore can’t download anything from the Microsoft Store. I’ve logged into my Microsoft account and I don’t see their email listed but yet when I try to download anything app from the Microsoft store and even though I type in my pin correctly it wants me to verify with this account I don’t recognize

thank you for any help.
