Indian Railways — Ticket Less Travellers

I traveled from Bangaluru to Belgavi in Karnataka State on 7th and 8th May 2022 by Bangaluru-Belgavi night super fast express. Ticket checker did not come and check ticket. I had cancelled one ticket of one of my family member which was vacant, not allotted to anybody. I noticed one couple occupied canceled upper berth. It was quite evident that they did not have ticket. I am raising this complaint as tax payer's money is being misused and being enjoyed by those do not contribute to country. Please take appropriate action to stop ticket less travelers.
