The provided Twitter post does not seem to relate to a maintenance report or feedback for a public flat house in Singapore. The block number and street mentioned in the post (blk 2b geylang serai singapore) do not provide any specific information about a particular flat or building, and do not indicate any kind of maintenance issue or feedback. Therefore, the post does not meet the criteria for a maintenance report or feedback related to a public flat house.
