Ah, you are so right! My bad
I was retained by the police when they stopped my for speeding(did not receive any speeding ticket at the final), was arrested for a few days because was a holiday season any my procedure did not move.
I received a Exclusion Order(IMM 1214) removal and I do have Inland Enforcement officer confirmation of departure, notice of removal(BSF560), Unescorted removal.
Also, I did followed all the protocol procedure, left the country at the time and did not try to speculate the process.
