Christian Medical College — not letting me in even when I am having appointment

Address:

CMC vellore, Vellore, Tamil Nadu, 632004

I was having the appointment letter at that time but the security guard of opd b.30 stopped me at the gate and told me to call one of my family member who is already inside, when i called my father the security gard talk to me in a very rude way and said when already your father is inside then why you want to go inside, i mean really?
What's wrong with that security gurd? People are coming very from their home town for treatment, please tell that insane security gurd not to behave like that... It affects the impression of the hospital, thanks... (Timing 12:00 pm)
