Indian Railways — TTE accepting bribe and giving berth to passengers without ticket

My Family travelled in train no 12601(Chennai to Mangalore) in S1 coach On 20.02.2022, TTE accepted bribe and gave berth to passengers without ticket and also didnt allot any berths to RAC passengers. i registered a complaint on indian railways at 139 on today morning(21.02.2022). Railway staff called and enquired in a bad manner and also they are supporting TTE. i got a reply from railways that the berths which i mentioned were vacant but as it was till caicut, so they couldnt allot it to my family. Calicut is one stop before our destination station(vadakar) and it usually arives at 7.27am. Sleeping time at INDIAN RAILWAYS is only from 10pm to 6am(correct me if iam wrong) How officials are supporting this kind of bribery action without any hesitation that too in official site. Officers were giving wrong informations to me on call too. i need complete refund for 2 tickets as 2 people managed in 1 berth and also a proper action against TTE as this is frequently happening.
