I'm sorry this has happened to you. It sounds a lot like what happened to me with FB over a year ago and I never got my account back. I tried appeals and emailed them numerous times. They did not even give me the courtesy of a reply. In my case, it was incredibly ridiculous. I posted a few videos of my kids doing covers of a few popular hits and gave credit, etc. They did well and had over 10,000+ organic views. I got a warning, then maybe another, so I removed them from my personal page, but forgot to take them off their band page. Well, they disabled my personal account. Because I had given access to their band page to a couple of others, that was not lost. I am not sure that they will give it back to you but wish you the best of luck getting it back. Please report back with any developments.
