While checking our upcoming Facebook integration updates, we were going through a few of our client's Facebook pages. What we noticed was many of them had information that was inaccurate. An example was the country of the shop were listed as Russia, others had categories which did not make sense e.g. a newsagency was listed as a cake shop, the email address on another was incorrect, etc. When we investigate it became clear that these were old pages that people had set up and had forgotten about. Many of them actually now had new pages. The problem was that the old pages were still there and if someone goes looking through Facebook, the odds were that they would find the wrong page.
My advice is search for your Facebook page and make sure that it is right. If you no longer have the password, and the email address listed you may have problems.
