What are my rights after an 8-hour Batik Air Malaysia delay?

Hi everyone, I was on Batik Air Malaysia Flight OD1006 (KUL–BKI) on Sept 3. The flight was scheduled for 7:00 PM but only departed at 3:30 AM on Sept 4 – over 8 hours delay.

Problems: • Passengers were boarded and then forced off due to technical issues. • While waiting onboard, no air conditioning was provided. The cabin was extremely hot, kids were crying, and elderly passengers were struggling. • Staff showed no empathy and were even sarcastic when people raised complaints. • No proper communication, no arrangements, no compensation.

I’m looking to file a complaint and request a refund/compensation. Does anyone here have experience with Batik Air Malaysia or with CAAM / Malaysian aviation authorities? What’s the best way to proceed?

Thanks in advance!
