It seems that the tweet provided does not relate to a maintenance report feedback for a public flat in Singapore. The tweet simply mentions "tan wah heng department store singapore sg" without providing any context or information related to maintenance 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.)?"
