Facebook delete page link to my personal account

Dear Experts

I have a personal account and I linked one page of my business to this account.

Now I want to create another facebook account for business and link that page to it.

whenever I create a business account ( which is same name as my page) and login to it directs me to my personal account.

I deleted that page and still business account redirect me to my personal account

What had I done wrong ?

Thanks
