    ]

It seems that the post does not mention any specific issue or feedback related to a maintenance report for a public flat in Singapore. The post only mentions "posted video east region Singapore" without providing any context or details related to maintenance or housing issues. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
