It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The word "drop" is not a term commonly used in maintenance reports, and "Rainbow Centre" is not a government agency or facility related to public housing in Singapore. Therefore, the post does not meet the criteria for a maintenance report feedback for public flat house.
