this is how the malaysian behave, also to the rest of the world. even you stay on landed like terrace or semi-d, you will still hear the noise like door banging if your neighbors are inconsiderate. i myself really dislike neighbors bang doors and play loud music. the best is live in bungalow. after my retirement, i plan to move to bungalow, especially unit like single storey bungalow at kampung place, but im not sure kampung kids will be the another disturbance or not.

you complaints may remain unresolved. Condo MC will only act as advisory to ask them be more gently and lower the noise, and it subjects to the neighbor them whether to accept the critique. most of the time they wont. if you ask for any suggestion here, i would say you can annoy them easily since you stay above them. by doing so you make no difference to them. i myself will fight it back to them after several times of soft approach and this is the only method that is effective.
