My former Apple id keeps popping up while using my iPad (asking for password to iCloud). I want to remove the old I'd but Don't know password. Called Apple support and they won't do it for me unless I either identify myself via birthdate (my birthdate won't work) and mother's maiden name which works. Also, when using email option to get instructions how to remove old I'd, the email message never shows up in my in box or junk mail. Apple says I probably never verified the email address. They also said if I could prove ownership of any of my apple devices that might help. None of my serial numbers match what they have on record. I thought maybe it was registered under my wife's name and that didn't't work either. So, I sit here with 11 Apple devices and apple won't help me remove my old Apple id! What can I do?
