I have an account of had eight years. I got locked out of my account saying that they were multiple users. The email that I use for this account no longer exists and I definitely don't remember the password. So I purchased another phone set up another Facebook account and today I got locked out of it because they said that I wasn't who I was saying I was my first email address that I used was RB *** ** at gmail.com that does not exist anymore okay then you and that I open that I was blocked out of the email is *****@***.com the phone number for the first account is *** *** ****. For the New York app that I just opened yesterday that I'm locked out of my phone number for it is ***-***-**** could you please let me get into my account or at least delete the first account and let open the second account
