Changi Airport Group review: The officer of t2 arrival staff entrance afid

When SQ informed me to collected my lost and found item from SQ25 landed on 6 Jan morning on 7 Jan at T2 arrival Lost and Found counter. I follow the instructions to proceed to T2 arrival staff entrance to enter the restricted area. This officer Afid was attitude, when after check my bag and body screening by a lady officer this officer Afid just in front of me talk to lady officer to” tell her stand to another side”. I thought i can collect my passport back after registration, however total 3 officers no body bother to explain what is the procedures for me to collect the found item. I think as officer in airport you should give correct attitude and explain correctly to the passages. Changi Airport is the number 1 airport in the world, how can the Certis officer behave like gangsters. When I exist the time they just tell me go out “ there, there” where is the professional of the officer? They are not police officer and we are not criminals. When I check for his name this officer Afid ignore me 3 times and do not want to talk to me. investigate and I want apologies from this officer.
