The post does not relate to a maintenance report feedback to a public flat house. The location mentioned in the post (Mandai, Singapore) is not a specific block or street, and does not provide any information about a broken facility or inconvenience in a public housing estate. Therefore, the post does not meet the criteria for a maintenance report feedback.
