It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The post mentions the Newton MRT interchange and the block number (NS21) and street (DT11), but it does not contain any information about a maintenance issue or request for fixing. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house in Singapore.
