Hello guys, I would like to know more about a person who might be an "Orientation Committee" or "security guard" etc who called himself "D.M.".

Situation:
Today I was in the first Orientation Day and in the hall, someone was giving speech at the stage. During the speech, I received a message and needed to leave emergency for personal reason. So I asked one of the OC and he brings me to meet a guy who wears coat and hold a talkie. I explained my situation and tell him I may or not come back. He ask me am I staying hostel and yes I was taken the temporarily stays. He asked for my student ID and asked about the time I will be back, so my ID taken. And I told him I will be back in 10pm, he said he wanted me to promise him and must see me in 10pm. Then I leave the hall.

Back in 10pm, I went back to the same place and asked one of the guy who dressed like an O.C. He called someone and asked me to wait. Few minutes later the guy who taken my ID came into me and told me the ID was sent to my faculty. And ask me to come back in the morning. I tell him I'm not going to stay in hostel and not coming back tomorrow in the morning. He asked did I get permission from my faculty's head? Huh?! I say I don't know what he talking about. He walk back in the door and I was waiting outside. The other OC who I met he returned my ID and say thank you and wish me enjoy the class on 3rd June. And the DM came out and didn't look at me at all and passed by with an unsatisfied face.

And I went back home with my student ID.
Sorry my words too long...

MU QUESTION IS:
Does he have the rights to hold a student's ID which doesn't belongs to him?
The student ID clearly stated "This pass is not transferable" and "If found please return to Admission and Bursary Division"

I felt I'm being bullied, so I am going to write a complaint letter about him.
Does anyone faces the same case like me before?

Thank you.

i believe it is the one at FCI, glass room

First three no need la. Tahap pengajian is your program. You doing degree or fosee or what? Need more details. Tarikh mula pengajian is the date you start your program as stipulated in your offer letter. No. Matrik is pretty straightforward don't you think? lol. Your student ID number.
