Indian Railways — misbehaviour with lady passengers

We were travelling from mathura to mumbai via august kranti train in 2 tier a. C. On 6th dec. There were group of gents completely drunk and were misbehaving with ladies and made noise whole night till they got down at vapi station.
We pay premium charges in this train and that too 2nd a. C. For our safety but the purpose is defeated. We need more security and checking as they were drinking mixing in thumps up bottle.
Please advise what action you are going to take
