Didn’t save all contacts – My Contacts Backup Review

I have an exchange acct that I need to delete and for some reason most of my contacts are linked to it. It is an old work account so I don’t know how my personal contacts are linked to it. I used the app to backup my contacts and some were still missing and I had duplicates of others. Some I lost the name on. The initials were still there but no name.
