Indian Railways — unreserved people rushed into the reserved compartments (sleeper class)

I am travelling in daulatpur chowk intercity express 19717, s1. I'm a regular traveler, if some critical situation may happen this is how you treat people?
Please shift people without or unreserved tickets to general or at least remove them from our seats which i bought. Everytime people who don't have any tickets rushed into reserved compartment if we told them to vacant our seat, they replied with a reason that they get off from train when there station arrived or you've to manage at least 30 minutes then they'll vacant our seat. We're not fool that we book tickets about a month ago for comfortable travel. But there is condition in the sleeper class compartment that is filled with unreserved people and we reserved people are just saw them sitting on our seats. It always happens, most o[censored]nreserved people enter in compartment on gandhi nagar railway station and they give reason to travel until alwar junction. Kindly please solve this issue soon.
