The posts on a social network site are different from the profile that can be modified and deleted anytime. To delete a Facebook page, look for the option buttons Page Visibility, on the top where one can Unpublish the page's posts on the site by going to the Settings and saving changes. You can republish it over again by modifying the Settings. In addition, you can amend the Remove page option where the message shows the content will be removed after 14 days of confirming the request.
