Facebook Specialist

We need someone who is able to solve an issue we have been having with our Facebook page. Essentially, we seem to have No Admin for our page. The only person who manages the page/ account is down as an editor. We have no idea who set up our page or who might know about it. We cannot seem to find a solution online and cannot of some reason, get in contact with Facebook Support. Due to this issue, we cannot link our Instagram account fully and manage that from the Facebook Business Suite or Business Manager. It will also not allow us to run ads on this account/ page because of this. Nor does it even if us the option of changing admin and there is no history detailing any information on this problem in our Facebook Page Management History
