It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The term "sixth cafelink singapore" does not appear to be a recognized term related to public housing or maintenance reports in Singapore. 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.)?"
