I am unable to login to facebook

Well I don't even know where to start. I am beyond locked out of my account and when I say literally no verification process works, nothing works. I get all my friends photos correct fails. I get my comments correct fails. I change pass word fails. I try and use a new device as that is what it asks for FAILS. It kept saying login expired and thought some one was hacking me well no one was hacking me. I reset my password 20 times probably in 2 weeks and now I just cant do anything. There is no customer service or anything Facebook is trash. Now I am stuck not being able to use my business pages, lost of family and friends and photos. Awesome!! Good job facebook
