Cisf — entry denied at terminal 3 arrival to go air pilot with aep for all airports

Dear sir,

I am flying for goair and as you are aware we operate from terminal 2. Due to lack of food outlets at arrival i often go to terminal 3 arrival to eat after operating my flight.
Today, 23/12/2017 at 0120 hrs i was denied entry in a rude manner by the guard at gate 1. I then called the inspector in charge to request but he also told me that in spite of my current aep i cannot enter. Name of inspector abhishek kumar
I demand explanation, on what basis entry was denied to me.
Regards
Amarinder sandhu
