Why all the contact numbers in my device is lost?How should I recover it?

I am trying to clean my Samsung Galaxy Note 3 repeating contact list, where I select " Merge with google" in the Option Bar, many of the contacts photos I have previously set suddenly disappear. I later try to remove the google account to undo the merges. It ends up all my Contacts in Device are lost! leaving some whatsapp contacts. What happens? there's thousand of contacts inside. Please Help me.
