Facebook complaint: Hacked

I am not an impolite person…I have many friends…When I created my Facebook account, I had over 1,100 friends on my list…One day as I was trying to log into my account, someone was on there at the same time, moving things around, changing my password, posting things on my account, that I, personally, would never post, and several of my friends and relatives have asked me about it… I can no longer get into my account, nor can I even find it when I look under my name…They have changed everything and I have no idea why….My password, my e-mail address, my phone number, everything… I have reported this to Facebook several times and they keep telling me the same thing… They don’t feel my account has been compromised, therefore, there’s nothing they can do to help me out…I have many dear friends and relatives on my account that have passed away, my 14 year old daughter, included, so this upsets me very much… I want my account back, I want to know who stole it, and I want to know why…How can somebody be so rude, as to interfere with someone’s social life when they’re not doing anything wrong??? Please tell me there is something you can do to help me, to find this imposter and get my account back… Facebook has canceled every other account I’ve tried to make after this and I don’t know why, or at least someone has…I really hope you can help me out!!!
