Indian Railways — unauthorized access to preserved body of the train by general and without ticket passenger

We are traveling in the reserved bogy of intercity express from vishakhapatnam to bhubaneswar on 30th december 2019 which departed from vishakhapatnam station at 3.25 pm. After 2/3 stations some passengers without proper ticket forcibly entered into the bogy. While telling them our inconvenience they argued so harsely. We needed the help of tte. But he is not available in our only reserved bogy of the train. As per my knowledge no general passengers can enter into reserved bogy. We reserved passengers are facing so much problems..
