Is about two weeks now since I can not access my facebook account, I opened my facebook only for me to discover that am loged out, even when it is on ''remember pasword'' trying to login they told me that the pasword is not correct, And am sure that the pasword is correct. then trying to use ''forget pasword'' option, they told me that they have sent confirmation code to my phone, but it does not come to my phone, which means that the hackers has also change my phone number. please what can I do to retrieve my account?
