Facebook complaint: Locked out and cannot delete account

I forgot my password to Facebook well over a year ago and since I basically never use Facebook, I didn’t do anything about it. This August I tried to reset my password so that I could just shut the account down. Facebook indicated they would send a code to my email. I entered the first code sent and then it proceeded and all of the sudden went back to the beginning and said I needed a code. From that point on it kept indicating it sent a code but no code every came to my email. After I tried 3 times to get a new code, the system locked me out. Facebook would not accept the ID I sent – they aren’t exactly trustworthy with information so I find it rich they even ask for it. I’ve sent videos of myself speaking to them, photos of myself in frames around my house, photos of me with my facebook friends, described my account, offered to take a video call with them – nothing. Radio silence. All I want is to remove the information and shut down my account. They’ve even banned me from sending them information. They offer NO way to contact them and won’t engage. Literally I have not used this account in over a year – why is it a big deal to just delete it and send me a verification? Why can they control my personal information?
