Indian Railways — Missed train due to overcrowding

We have 4 reservation seats in the coach D11 in Taj express dated 30th Aug 2023 . We have reached the station 7 am and train timings was of 7:26 am . When the train arrived it was unbelievably overcrowded. We tried with our full potential to board the train but it wasn't possible to board the train . Reservation coaches was full with the non reserved passengers . I don't know why TT was allowing the people without reservation to travel. When the train started, there was a TT at his coach whom I asked to stop the train by giving signal but he blamed us that we don't know how to board a train . It was very unfortunate to hear this out that we have to first get trained for boarding the train . It means you shouldn't have tickets to reach your destination instead you should how to hang on doors and windows to reach the destination.
