Indian Railway Catering & Tourism Corporation [IRCTC] — tt sold our seat to another passenger and showed unethical behaviour with elderly passenger

We were travelling from nzm to shahdol, on train chhattisgarh smapark kranti (12824) had 4 seats in a1 coach on seats 37, 38, 20, 22 on 28th of april, one o[censored]s couldnt board due to some official reasons. Tt ashok kumar checked our seats and went away. As we had only one lower seat on our ticket, with us, my elderly mother along our small baby slept on one of our lower seat and we had our seats in another coupe on upper births, left for our respective seats. Around midnight, one of the passenger along with the couch attendent came to her and started shouting at her very badly for leaving her seat immediately, as this seat was sold to another passenger, he started behaving rudely, arguing with her. Other passengers around that seat also raised an objection for shouting at her, as she was sleeping with small baby. Other passengers were concerned. She told them that this seats belonged to us, how come is he asking for that seat. Then, as one of the seat above this lower birth also belonged to us and was vaccant, since one us hadnt board the train was vaccant. My mother and other copassanger was somehow able to convince him to sleep on the upper birth and slove the matter in morning. Morning, when we returned back to our seat, the coppasengers told me what happended in mid night. When we asked to passenger why was he claiming our seat, he told us that tt had aksed him to sleep on our seat. When i asked him for the ticket, he denied showing us the ticket, in sometime, he came back along with a tt, i asked, how did he sold our seat and didnt inform us about selling our seat. He said, its his fundamental right to sell anyones seat to anyone else and no one can question and he need not imform to anybody. I told him, its his moral or ethical duty to atleast inform us, incase, one o[censored]s didnt board, we dont know, which seat belongs to which one us. He wanted to sell the seat, thats fine, but atleast should let us know, becasue rest of the passengers have boarded only except one. But he kept arguing us badly, and shouting in the whole train for about an hour, he kept wandering around us and threatening. He wasnt wearing his tt dress and when i asked him his name, he said ashok kumar. On asking full name, he didnt reveal, since he wasnt wearing his dress on duty. I told, him that i am going to complain this matter to higher authority, he said, complain to whoever you want. We were feeling very disappointed, that one is not safe, even they wont spare an elderly and a small baby for their profit. The seat was sold, the passenger didnt have a valid tciket with him, tt was forcing him to sit on our seat, where we were sitting initially. But later when i asked him for ticket, he ran away and didnt show up. After some time, we had to deboard our train at shahdol. Please note this is a serious note and tt should be tought moral values how to behave with passengers and server their duty rughtfully. Pls find one video i could manage to capture. See the video, how he ran away, when i was asking him for the ticket.
