It seems that the tweet "uncertainty marsiling singapore" is not related to a maintenance report feedback for a public flat house. The term "marsiling" is likely a misspelling or a non-standard term, and it does not seem to be a recognized term in the context of public housing or maintenance issues in Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
