Complaint Against Hospitality By Malaysia Airline

For my academics purpose i have booked a return ticket for japan from india in March whose BOOKING REF. is 46YNMI.During coming to japan from india there was a 16 hour stop in kuala lumpur. For this longer stop flight they charged me more than the flights having 3-4 hour stop.I paid more amount for this long stop so that i can get the facilities during this stop but Malaysia airlines hadn't provide me any hotel room or any food during this stop and i paid myself for all the things.I have inquire about this and i came to know that in my case because the stop was too long (16 hour) the Malaysia airline was liable to provide me all the facility As they already charged me more but they didn't provide me the facility.Sooner i am going to file a complaint against Malaysia airline in the CONSUMER COURT.
