It seems that the post does not contain any information related to a maintenance report feedback for a public flat house in Chennai or any other location. The post only mentions the location "Chennai, Tamil Nadu, India" without providing any context or details that could suggest otherwise. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
