It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The handle "ntuc fairprice singapore" does not appear to be associated with any official government or housing agency in Singapore, and the post does not contain any information or keywords related to maintenance reports or public housing. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house (e.g., a broken facility, an inconvenience, block number or street, requst fixing, etc.)?"
