It seems that the Twitter post you provided does not relate to a maintenance report feedback to a public flat house in Singapore. The term "Hell Boy" does not appear to be a reference to any specific maintenance issue or facility in public housing estates, and the location mentioned ("Jurong West, Singapore") does not provide any specific context for the post. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
