Air Asia — cabin crew

Good day!
I am writing this letter to inform you about my complaint during my flight with air asia. My flight details z2 767 from manila (Ninoy aquino international aiport to cebu (Mactan-cebu international airport) last september 23, 2017. The flight was delayed for 30 minutes but it's not a big deal for me. Since we had our take off for almost 7:00 pm in the evening already. I've been having several trips with other airlines and i think for air asia it's my 2nd or 3rd time to book a trip. As expected based on my previous experiences as we take off after the seat belt lights are off, lights are dim already and we can also inclined the chair to have a comfortable and good rest during the flight. But then to my surprise, the cabin crew are so noisy that their voices are so loud during their conversations and they even laugh so hard. It was so irritating that i wanted to take a nap but then i can't make it because i can hear their loud voices. All through out the trip talking and laughing with very loud voices is what the cabin crew did. As if they are the only passenger inside that aircraft. I wanted to call there attention but then i'm in the 28th row and other passenger is asleep already so i waited maybe after a while they will lower down their voices but it never happened. It was my worst flight ever. Hope you will take actions with regards to this matter.
Thank you and have a good day.!
