It seems that the Twitter post "pink causeway 0 singapore" does not relate to a maintenance report feedback to public flat house. The term "causeway" is a road or bridge, and "0" is likely a location or address, but it does not provide any information about a maintenance report or public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
