It seems that the provided Twitter post does not relate to a maintenance report feedback to public flat house in Singapore. The post simply mentions the name of a venue in MacPherson, Singapore, which does not provide any information about maintenance or housing. Therefore, the answer is a JSON object with "relatedness" set to "False", "type" set to "none", and "explanation" set to a short explanation that this is not related to public housing or maintenance report feedback.
