Facebook Keeps Opening the Wrong Account on iPhone After Hack

I have been experiencing a serious problem with my Facebook account on my iPhone for more than five months. My original Facebook account, whose user ID is 411934121, appears to have been hacked, and the phone number linked to it was changed without my consent. Since then, whenever I try to log in, the system takes me to a different account instead of my original one, even though I am trying to access the same old profile. I still remember the original contact details (email/phone) that were linked to my old account before it was hacked, but despite trying to log in and follow the on‑screen steps, Facebook keeps showing and opening the new account instead of giving me access to my hacked account. Because of this, I have completely lost access to my original profile and all my data there. I kindly request that my old Facebook account with UID 411934121 be recovered and access restored to me as the rightful owner. I want the incorrectly linked account to be removed from my login attempts and my original contact information to be reconnected to my real account so that I can use it safely again.
