My friend has recently tried so many different methods of fixing her problem but was unsuccessful because she has forgotten her password to her account and does not have access to the email or phone number registered with the account, so the problem is there is an account that she has set up a couple years ago and last year lost access to it and she’s unaware if this is because of her ex boyfriend blocking her by changing the password or doing something different to the account, she has had a hard time ever since she’s been unable to access this account, all she wants to do is delete this account because she doesn’t want that account to be on Facebook anymore, can you please help me or help her directly, her name is dayle olivia weller and she does not have another Facebook account because she deleted it as she doesn’t want to use Facebook anymore due to religious reasons. I really wish that you are able to help and help her delete this account so she could move on and become in a happier mental state.
