What's the difference? They were sent to you yesterday? They have been sent to you yesterday? Which one is correct? Can I add "yesterday" to "have been sent to you"?Can I use them both?What's the difference? Thank you.

At the tense of Present Perfect you don't use "yesterday". They have been sent to you. They had been sent to you. They were sent to you yesterday.
