It seems that the Twitter post "bright nights katong concourse" does not relate to a maintenance report feedback to a public flat house. The term "katong" is a location in Singapore, and "bright nights" could refer to a variety of things, but it does not provide any information about a maintenance issue or feedback related to public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
