I'm sorry but that doesn't make any more sense. Who is "he?" What do you mean by "a google person?"

What are you seeing that you want to fix?

What do you mean by "unlink accounts"?

So you're sharing an Apple account with someone?

Perhaps you should try posting in your native language and actually explaining your problem.
