I try to amend my contact details but the old details keep coming back
One of my IPad contacts is nicknamed "me". It contains a few old email addresses and also some email addresses which are nothing to do with me, such as some Facebook groups. I go into edit mode and delete all these addresses but after a while they all come back. This has happened several times. These email addresses also show up on auto fill. How can I edit this contact permanently.
