You seem to not understand you are NOT speaking with Apple. No one here is refusing anything, because no one here on this user to user only forum works for Apple.
The policy is what it is. You had 14 days post purchase to return the phone to Apple for another product. Apple is not accepting iPhone 11 for trade it at this time. That may change when the new phones are released, but today, you cannot trade your phone into Apple. And we users have no control or influence with Apple at all.
Also as has already been pointed out, even when Apple does accept iPhone 11 for trade, you will do better by selling it on the open market.
