Taj Hotels — Misbehavior by security staff

I am staying in room number 508 of Taj, City Centre 2, Kolkata in room number 508 and the security person at the entry gate misbehaved with us and refused entry for almost 15 minutes... When I entered the hotel and tried to lodge a complaint, I was not given any assistance and told that they had no system of accepting a written complaint.
