some one hack my page through Social Advertiser. He ask me to add him in my Sponsoreds Ads ’s business account to help me regarding creation of ads. So I trusted him and add him as a admin. But after that given him access to Sponsoreds Ads ’s business, he made themselves admin and deleted all the other admins. The page is now up but under the hacker's admin.
i complaint many time to facebook help center and reported the page that it is pretended to another person but untill now I don't get any help.
