Indian Railways — My berth was given to another person

I booked a berth in westcoast superfast express from tirur (Tir) to mangaluru cntrl (Maq)
And my berth was given to some another person without my consent and the ttr told me to take that person's seat.. When i complained to him he told me to adjust with what you are given and no alternate solution was provided. Iam not at all satisfied with this attitude of the official because i truly believe that indian railways treats the people in a good manner. And seeing this aptitude its really hurting
