when i make transaction i also access with seed,i am 100% sure about this,i cant explain
No. You are 100% wrong.
You NEVER access your nano s with your seed. You only initialize it ONCE.
Each time afterwards, you are accessing it with your pin. Your seed is stored inside your ledger.
Without having any clue, at least listen to us. You are repeating yourself. Your coins are gone. You have used the wrong seed.
Take it as a lesson and move forward.
