normally after we report the defects, how long does developer take for fix it?

just want to know
is there any case developer just ignore the defect even after you submit proper defect report?

Hi lowyat team
I really need help

I have leaking issue (roof to ceiling) on my main bedroom
Developer come fix it, but just using simple glue and replaster it.
When heavy rain, it leaking again

Is there a way to fix this proper way? like finding external contractor to fix it as seen my developer only come and glue and replaster it?
It really tiring and almost 1 month already i cant even use my main bedroom as this leaking issue
