It seems that the post does not relate to a maintenance report feedback to public flat house. The term "paynow" is not a specific term related to maintenance or public housing, and it does not provide any context that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
