My husband's iPhone 7 Plus was not working properly (microphone often did not work). Phone was replaced. I backed up original phone to iTunes. All apps worked perfectly on original phone. On restored phone I cannot open his Facebook account or FB Messenger. When I enter his FB login a new empty account opens. When I do a search for his name, in from my Facebook page, his name display three times. One has his actual profile picture. The other two are empty accounts with no profile picture. I worked with AT&T Pro Techs for over five hours without success. I have emailed Facebook, but I have no idea how long it will take to receive a reply.
How can I get rid of the two fake accounts and open his real account? His userid is his mobile phone number. He has only ever had one mobile phone number.
HELP my husband is going through extreme withdrawal.
