Facebook Opening New Account Instead of Old

I have been facing a problem with my Facebook login on my Android mobile phone. I have an old Facebook account with the ID 1192949***, but when I try to log in, Facebook automatically opens a new account instead of my old one. I created this old account directly through Facebook, and I now want to access only this old account. I do not want the new account that is opening automatically; I need my original account back with all my previous data and connections. I kindly request that my old Facebook account with ID 1192949*** be restored and made accessible to me again, and that the new account that opens automatically be cancelled or disconnected from my login so that I can use only my original account.
